cgroup: make cgroup_path() not print double slashes
While reimplementing cgroup_path(), 65dff759d2 ("cgroup: fix
cgroup_path() vs rename() race") introduced a bug where the path of a
non-root cgroup would have two slahses at the beginning, which is
caused by treating the root cgroup which has the name '/' like
non-root cgroups.
$ grep systemd /proc/self/cgroup
1:name=systemd://user/root/1
Fix it by special casing root cgroup case and not looping over it in
the normal path.
