kmod: drop leading + from getopt

From the man page:
  If the first character of optstring is '+' ... then option processing
  stops as soon as a nonoption argument is encountered.

In all fairness, I'm not sure if we want this behaviour. Especially
since no other kmod tools use enforce such behaviour.

Drop it for consistency-sake.
