Special-case "su --help".

Rather than force people to move from "su system echo -n hello", where
the -n gets interpreted by getopt_long(3), to "su system -- echo -n hello",
just hard-code the recognition of --help. This seems easier than moving
people over to the more traditional "su -c 'echo -n hello'" style.
