This function was added in ae22854e2b, but never
returned an error, and the error-return was not handled on the callsite. This
patch removes the unused error return, and moves it to a file related to mounts,
which allowed for some of the stubs to be removed and shared between non-FreeBSD
platforms.

A domainname field was recently added to the OCI spec. Prior to this
folks would need to set this with a sysctl, but now runtimes should be
able to setdomainname(2). There's an open change to runc at the moment
to add support for this so I've just left testing as a couple spec
validations in CRI until that's in and usable.

But it depends GitHub actions' performance.
In addition to that, this commit extracts the script from ci.yml.

This patch requests the OCI runtime to create a userns when the CRI
message includes such request.

This allows user namespace support to progress, either by allowing
snapshotters to deal with ownership, or falling back to containerd doing
a recursive chown.
In the future, when snapshotters implement idmap mounts, they should
report the "remap-ids" capability.

As explained in the comments, this patch lets the OCI runtime create the
netns when userns are in use. This is needed because the netns needs to
be owned by the userns (otherwise can't modify the IP, etc.).
Before this patch, we are creating the netns and then starting the pod
sandbox asking to join this netns. This can't never work with userns, as
the userns needs to be created first for the netns ownership to be
correct.
One option would be to also create the userns in containerd, then create
the netns. But this is painful (needs tricks with the go runtime,
special care to write the mapping, etc.).
So, we just let the OCI runtime create the userns and netns, that
creates them with the proper ownership.
As requested by Mike Brown, the current code when userns is not used is
left unchanged. We can unify the cases (with and without userns) in a
future release.

When images/containers in ARM arch were built/executed on x86 host,
getCPUVariant will fail as it tries to look for /proc/cpuinfo, whose
content is from the host. Adding a new method as fallback to check uname
machine when it happens.

Due to when we were updating the pod sandboxes underlying container
object, the pointer to the sandbox would have the right info, but
the on-disk representation of the data was behind. This would cause
the data returned from loading any sandboxes after a restart to have
no CNI result or IP information for the pod.
This change does an additional update to the on-disk container info
right after we invoke the CNI plugin so the metadata for the CNI result
and other networking information is properly flushed to disk.
