Subject: [PATCH] add additional errno (INTR) to tcset,getpgrp calls

Missed this originally because I was only able to trigger it when
SA_RESTART was missing from the sigaction handlers. I'm unconvinced this
is actually a sane way for stdlib to behave (see #15664). But this does
duplicate the existing behavior throughout os.zig which IMO should be
prioritized here.
