xtables: Improve xtables-monitor first impression
First time users are likely to call 'xtables-monitor --help' to see
what's going on. Make this situation a bit more pleasant for them:
* When complaining about illegal arguments, add a final newline
character to the error message.
* Actually support '--help' long option as an alias to '-h'.
