Subject: Change the behaviour of adduser to match the previous incarnation a
 little more.

If any of the given groups do not exist complain and let the user try again.
This saves the user from discovering at the end of the process that they've
forgotten to add a group or they've typoed.

Thanks to cmc/dougb for pointing out how bad my sh fu actually is.
