su: don't use kill(0, ...) when propagate signal
The current code uses kill(0, caught_signal) after regular
signal cleanup and before exit (all just to make shells happy).
Unfortunately, kill(0, ...) is a bad idea. It seems better to use
kill(getpid(), ...) otherwise we kill our parent process too.
