ubi-utils: Return error code if command line option is unknown
The tools in question will quit with an exit code 0 if the command line option was not recognized. By returning an error code a calling script has the possibility to distinguish between a real success and an invalid invocation. We need to return -1 instead of EXIT_FAILURE to be consistent with the other exit code places.
