It appears that when we import github.com/coreos/go-systemd/activation,
it brings in the whole crypto/tls package (which is not used by runc
directly or indirectly), making the runc binary size larger and
potentially creating issues with FIPS compliance.
Let's copy the code of function we use from go-systemd/activation
to avoid that.
The space savings are:
$ size runc.before runc.after
text data bss dec hex filename
7101084 5049593 271560 12422237 bd8c5d runc.before
6508796 4623281 229128 11361205 ad5bb5 runc.after

This new version includes the fixes for CVE-2025-52881, so we can remove
the internal/third_party copy of the library we added in commit
ed6b1693b8 ("selinux: use safe procfs API for labels") as well as the
"replace" directive in go.mod (which is problematic for "go get"
installs).

Due to the sensitive nature of these fixes, it was not possible to
submit these upstream and vendor the upstream library. Instead, this
patch uses a fork of github.com/opencontainers/selinux, branched at
commit opencontainers/selinux@879a755db5.
In order to permit downstreams to build with this patched version, a
snapshot of the forked version has been included in
internal/third_party/selinux. Note that since we use "go mod vendor",
the patched code is usable even without being "go get"-able. Once the
embargo for this issue is lifted we can submit the patches upstream and
switch back to a proper upstream go.mod entry.
Also, this requires us to temporarily disable the CI job we have that
disallows "replace" directives.
