[PATCH 2/4] cgroup/cpuset: Expose cpuset filesystem with cpuset v1 only

["Michal Koutný" <mkoutny@suse.com>]

The cpuset filesystem is a legacy interface to cpuset controller with
(pre-)v1 features. It makes little sense to co-mount it on systems
without cpuset v1, so do no build it when cpuset v1 is not built
neither.
