[PATCH v0 13/20] integrity: Return error code if command line option is unknown

[Daniel Wagner]

The tool 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.
