PR kern/58425 -- Disallow INT_MIN as a (negative) pid arg.
Since -INT_MIN is undefined, and to point of negative pid args is
to negate them, and use the result as a pgrp id instead, we need
to avoid accidentally negating INT_MIN.
Since pid_t is just an integral type, of unspecified width, when
testing pid_t value test for <= INT_MIN (or > INT_MIN sometimes)
rather than == INT_MIN. When testing int values, just == INT_MIN
is all that is needed, < INT_MIN cannot occur.
tests/lib/libc/sys/t_kill: Test kill(INT_MIN, ...) fails with ESRCH.
