[PATCH] signal: use kill_pgrp not kill_pg in the sunos compatibility code
I am slowly moving to a model where all process killing is struct pid based
instead of pid_t based. The sunos compatibility code is one of the last users
of the old pid_t based kill_pg in the kernel. By being complete I allow for
the future removal of kill_pg from the kernel, which will ensure I don't miss
something.
