Fix elog(FATAL) before PostmasterMain() or just after fork().

Since commit 97550c0711972a9856b5db751539bbaf2f88884c, these failed with
"PANIC:  proc_exit() called in child process" due to uninitialized or
stale MyProcPid.  That was reachable if close() failed in
ClosePostmasterPorts() or setlocale(category, "C") failed, both
unlikely.  Back-patch to v13 (all supported versions).
