bitbake: Updated the the example 'bitbake -h' output to match the actual output, which has been recently patched to fix the '-S SIGNATURE_HANDLER, --dump-signatures=SIGNATURE_HANDLER' option.

Note also, that I have added a new option that has since appeared
in the output but was not in the manual's example.  That option
added is '--token=XMLRPCTOKEN'.
