pam_cgfs: handle cgroupfs v1 cpuset controller

If init has not placed us into our own cgroup on login we will reside in the
root cgroup. In this case cgroup.clone_children will not have been initialized
and so we need to do it. Otherwise users will not be able to start containers
with cpuset limits set.
