We need these to match the Makefile detection of the right gcc for
runc-dmz, as well as making sure that everything builds properly for our
cross-i386 tests. While we're at it, add x86 to the list of build
targets for release builds (presumably nobody will use it, but since we
do test builds of this anyway it probably won't hurt).
In addition, clean up the handling of the native architecture build by
treating it the same as any other build (ensuring that building runc
from a different platform will work the same way regardless of the
native architecture). In practice, the build works the same way as
before.

This implements cross-build for "make release", moving the build into a
container. This way we can support arm, arm64, ppc, and whatnot.
* script/seccomp.sh: separate out of script/release.sh, amend to support
cross-compile and save needed environment variables to a file.
* Dockerfile: add installing libseccomp from source, as this is needed
for release builds.
* script/release.sh: amend to support more architectures in addition to
the native build. Additional arches can be added by specifying
"-a <arch>" argument (can be specified multiple times), or
"make RELEASE_ARGS="-a arm64" release" if called via make.
All supported architectures can be enabled via "make releaseall".
* Makefile: move "release" target to "localrelease", add "release" and
"releaseall" targets to build via the Dockerfile. This is done because
most distros (including Fedora and openSUSE) lack cross-glibc, which is
needed to cross-compile libseccomp.
* Makefile: remove 'cross' and 'localcross' targets, as this is now done
by the release script.
* .github/workflows/validate.yum: amend the release CI job to cross-build
for supported architectures, remove cross job.
