vl: Exit unsuccessfully on option argument syntax error

We exit successfully after reporting syntax error for argument of
--sandbox and --add-fd.

We continue undaunted after reporting it for argument of -boot,
--option-rom and --object.

Change all five to exit unsuccessfully, like the other options.
