pgsql: Remove obsolete comments about sempahores from proc.c. - Mailing list pgsql-committers

Remove obsolete comments about sempahores from proc.c.

Commit 6753333f switched from a semaphore-based wait to a latch-based
wait for ProcSleep()/ProcWakeup(), but left behind some stray references
to semaphores.

Back-patch to 9.5.
