Remove dependency of systemd units, services and slices for new sessions.

* elogind does not support systemd services and units. But at least
  the units are needed to support the systemd cgroup slice/scope
  system.
* Remove systemd subscription to scope, service and slice jobs.
  These can not be supported in any way, as they depend on systemd
  running the machine.
* The functions session_start_scope(), user_start_service() and
  user_start_slice() no longer try to call systemd via dbus for
  assistance.
  This way they generate their proper scope, service and slice names,
  and store them in the Managers HashMaps for session and user units.
  This should enable us to reverse track pids to users and such
  stuff, as that is what systemd-logind does, not knowing whether any
  unit *really* has been started or not.
  However, this will not work out of the box until we find a way to
  integrate cg_create_everywhere() into elogind without becoming
  dependent of systemd unit, service and job knowledge again.
