[COMMITTERS] pgsql: Remove long-obsolete catering for platforms withoutF_SETFD/FD_C

Remove long-obsolete catering for platforms without F_SETFD/FD_CLOEXEC.

SUSv2 mandates that <fcntl.h> provide both F_SETFD and FD_CLOEXEC,
so it seems pretty unlikely that any platforms remain without those.
Remove the #ifdef-ery installed by commit 7627b91cd to see if the
buildfarm agrees.
