killall(1): Handle -h and -? options as described in man page

As described in its man page, options -h and -? are supported to print
the help text, same as -help option.  However, it didn't work and
killall(1) gave such errors:

killall: unknown signal h; valid signals: ...
killall: unknown signal ?; valid signals: ...

While there, update usage text to match the supported options.
