Make WL_POSTMASTER_DEATH level-triggered on kqueue builds. If WaitEventSetWait() reports that the postmaster has gone away, later calls to WaitEventSetWait() should continue to report that. Otherwise further waits that occur in the proc_exit() path after we already noticed the postmaster's demise could block forever.
Back-patch to 13, where the kqueue support landed.
