Use an shmem_exit callback to remove backend from PMChildFlags on exit
This seems nicer than having to duplicate the logic between
InitProcess() and ProcKill() for which child processes have a
PMChildFlags slot.
Move the MarkPostmasterChildActive() call earlier in InitProcess(),
out of the section protected by the spinlock.
