Perform some basic checks for CHANGELOG.md.
In particular, check for
- missing periods;
- extra spaces at EOL;
- non-ASCII characters.
Fix the issues found.

systemd emits very loud warnings when the path specified doesn't exist
(which can be the case for some of our default rules). We don't need the
ruleset we give systemd to be completely accurate (we discard some kinds
of wildcard rules anyway) so we can safely skip adding these.

Add checking of downloaded tarball checksum.
In case it doesn't match the hardcoded value, the error is like this:
libseccomp-2.5.4.tar.gz: FAILED
sha256sum: WARNING: 1 computed checksum did NOT match
In case the checksum for a particular version is not specified in the
script, the error will look like this:
./script/seccomp.sh: line 29: SECCOMP_SHA256[${ver}]: unbound variable
In case the the hardcoded value in the file is of wrong format/length,
we'll get:
sha256sum: 'standard input': no properly formatted SHA256 checksum lines found
In any of these cases, the script aborts (due to set -e).

The CAP_CHECKPOINT_RESTORE linux capability provides the ability to
update /proc/sys/kernel/ns_last_pid. However, because this file is under
/proc, and by default both K8s and CRI-O specify that /proc/sys should
be mounted as Read-Only, by default even with the capability specified,
a process will not be able to write to ns_last_pid.
To get around this, a pod author can specify a volume mount and a
hostpath to bind-mount /proc/sys/kernel/ns_last_pid. However, runc does
not allow specifying mounts under /proc.
This commit adds /proc/sys/kernel/ns_last_pid to the validProcMounts
string array to enable a pod author to mount ns_last_pid as read-write.
The default remains unchanged; unless explicitly requested as a volume
mount, ns_last_pid will remain read-only regardless of whether or not
CAP_CHECKPOINT_RESTORE is specified.

This job is failing with "No space left on device" lately, and this
helps to fix it.
Besides, it seems that caching does not help to shorten execution times
(validate/release job succeeds in under 8 minutes now; ymmv).

On s390x, syscalls above 255 are multiplexed using the (now otherwise
unused) setup(2) syscall (syscall number 0). If the kernel supports the
syscall then it will correctly translate the syscall number such that
seccomp will correctly detect it -- however, for unknown syscalls the
syscall number remains unchanged. This can be verified by running the
following program under strace:
int main(void)
{
scmp_filter_ctx ctx = seccomp_init(SCMP_ACT_TRAP);
seccomp_load(ctx);
return syscall(439, AT_FDCWD, "asdf", X_OK, 0);
}
Which will then die with the following signal (on pre-5.8 kernels):
--- SIGSYS {si_signo=SIGSYS, si_code=SYS_SECCOMP,
si_call_addr=0x3ffb3006c22, si_syscall=__NR_setup,
si_arch=AUDIT_ARCH_S390X} ---
(Note that the si_syscall is __NR_setup, not __NR_faccessat2.)
As a result, the -ENOSYS handling we had previously did not work
completely correctly on s390x because any syscall not supported by the
kernel would be treated as syscall number 0 rather than the actual
syscall number.
Always returning -ENOSYS will not cause any issues because in all of the
cases where this multiplexing occurs, seccomp will see the remapped
syscall number -- and no userspace program will call setup(2)
intentionally (the syscall has not existed in Linux for decades and was
originally a hack used early in Linux init prior to spawning pid1 -- so
you will get -ENOSYS from the kernel anyway).

golangci-lint-action v3 no longer installs golang itself, and the
version that comes with Ubuntu is not new/good enough.
Install go 1.17.x explicitly.
Introduce GO_VERSION environment variable to avoid duplication,
and use it instead of 1.x in other places, so that implicit go update
won't bring some unexpected failures.

Unfortunately, fixing it results in an errorlint warning:
> libcontainer/factory_linux.go#L344 non-wrapping format verb for fmt.Errorf. Use `%w` to format errors (errorlint)
so we have to silence that one.

In case statfs("/sys/fs/cgroup/unified") fails with any error other
than ENOENT, current code panics. As IsCgroup2HybridMode is called from
libcontainer/cgroups/fs's init function, this means that any user of
libcontainer may panic during initialization, which is ugly.
Avoid panicking; instead, do not enable hybrid hierarchy support and
report the error (under debug level, not to confuse anyone).
Basically, replace the panic with "turn off hybrid mode support"
(which makes total sense since we were unable to statfs its root).

Don't require CAT or MBA because we don't detect those correctly (we
don't support L2 or L3DATA/L3CODE for example, and in the future
possibly even more). With plain "ClosId mode" we don't really care: we
assign the container to a pre-configured CLOS without trying to do
anything smarter.
Moreover, this was a duplicate/redundant check anyway, as for CAT and
MBA there is another specific sanity check that is done if L3 or MB
is specified in the config.

Apparently, not all files listed in /sys/kernel/cgroup/delegate must
exist in every cgroup, so we should ignore ENOENT.
Dot not ignore ENOENT on the directory itself though.
Change cgroupFilesToChown to not return ".", and refactor it to not do
any dynamic slice appending in case we're using the default built-in
list of files.
