logind: port over to use scopes+slices for all cgroup stuff
In order to prepare things for the single-writer cgroup scheme, let's make logind use systemd's own primitives for cgroup management. Every login user now gets his own private slice unit, in which his sessions live in a scope unit each. Also, add user@$UID.service to the same slice, and implicitly start it on first login.
