Stop bgworkers during fast shutdown with postmaster in startup phase

When a postmaster gets into its phase PM_STARTUP, it would start
background workers using BgWorkerStart_PostmasterStart mode immediately,
which would cause problems for a fast shutdown as the postmaster forgets
to send SIGTERM to already-started background workers.  With smart and
immediate shutdowns, this correctly happened, and fast shutdown is the
only mode missing the shot.
