ctdbd: Only start recovery daemon and timed events after setup event

This deconstructs ctdb_start_transport(), which did much more than
starting the transport.

This removes a very unlikely race and adds some clarity.  The setup
event is supposed to set the tunables before the first recovery.
However, there was nothing stopping the first recovery from starting
before the setup event had completed.
