 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.
