Put a service on into a top hierarchy of each cgroup
This change will fix unwanted cgroup inheriting from user cgroups,
and fixes issues with systemd cgroup tracking by logind.
However this fix can lead to incorrect work for some user cgroup
controllers - so more advanced solution, that coveres such cases
will be created later.
Thanks to Fabio Erculiani (lxnay) for testing and general idea.
