test-webkitpy: clean up logging and provide a real --help message

If you're not careful, you'll make this script actually work in a sensible way.
Committed r104841: <http://trac.webkit.org/changeset/104841>
I ended up reworking the --help text a bit and changing the default logging to log the info messages (like the fact that we were skipping scm_unittest by default); I figured that would be less surprising to non-experts who might run the tests.
