  start: CLONE_NEWCGROUP after we have setup cgroups

If we do it earlier we end up with a wrong view of /proc/self/cgroup. For
example, assume we unshare(CLONE_NEWCGROUP) first, and then create the cgroup
for the container, say /sys/fs/cgroup/cpuset/lxc/c, then /proc/self/cgroup
would show us:

     8:cpuset:/lxc/c

whereas it should actually show

     8:cpuset:/
