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
