libtracker-data: Add explicit shutdown call to TrackerDataManager

As DB interfaces will have a reference each on the TrackerDataManager,
callers will never drop the last reference themselves. Add an
explicit shutdown() call that just runs the dispose phase, and
destroy the TrackerDBManager on it.

Destroying the DB manager will tear down the writeable DB interface
and unlink the "is running" file. Any remaining readonly DB interfaces
presumably don't need the DB manager anymore and will disappear as
soon as all their remaining cursors are closed.
