 Modified Files:
 	src/tests/lib/libc/gen/posix_spawn: t_spawn.c
 
 Log Message:
 t_spawn: Add missing dup2 in t_spawn_sig.
 
 Matches what h_execsig expects, and what t_execve_sig arranges: stdin
 is a pipe that the parent will write a single byte to after it has
 delivered SIGTERM.
 
 Now this should have a higher chance of provoking the bug (though it
 was already good enough in cursory testing!).
 
 PR kern/58091: after fork/execve or posix_spawn, parent kill(child,
 SIGTERM) has race condition making it unreliable
