Subject: userspace: remove vestigial '?' cases from top-level getopt(3) loops

getopt(3) returns '?' when it encounters a flag not present in the in
the optstring or if a flag is missing its option argument.  We can
handle this case with the "default" failure case with no loss of
legibility.  Hence, remove all the redundant "case '?':" lines.

Prompted by dlg@.  With help from dlg@ and millert@.
