kill TIOCSER[SG]WILD

Al Viro · Al Viro · commit 7ee329655189 · 2018-10-13T00:50:52.000-04:00
the only user is very old setserial rc script and even that
(as far back as MCC Interim, AFAICS) doesn't actually fail -
just gives one message during the boot ("Cannot scan for wild
interrupts") and proceeds past that just fine.
