virtcontainers: Convert to the new cgroups package API

Browse Source 
The new API is based on containerd's cgroups package.
With that conversion we can simpligy the virtcontainers sandbox code and
also uniformize our cgroups external API dependency. We now only depend
on containerd/cgroups for everything cgroups related.
