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@.
