logind: release VT-positions when closing sessions

Make sure we release VT-positions when a session is closed. Otherwise,
lingering sessions will occupy VTs and prevent next logins from
succeeding.

Note that we already release session-devices when closing a session, so
there cannot be anyone using the VT anymore.
