buildman: refactor help message
"buildman [options]" is displayed by default.
Append the rest of help messages to parser.usage
instead of replacing it.
Besides, "-b <branch>" is not mandatory since commit fea5858e.
Drop it from the usage.

sorted at the end of the patch. However, this is not really necessary and
