CI: package_versions: include hostinfo, kernel

In the package_versions CI step, include Fedora/Ubuntu
version, uname -r, and cgroups version.

Cgroups version is simply the FS type of /sys/fs/cgroup,
which shows 'tmpfs' for v1 and 'cgroup2fs' for v2. I
don't think it's worth the effort to prettify those
into 'v1/v2' - I think our readers are sophisticated
enough to figure it out from context - but am willing
to add that feature if requested.
