patchtest: clean up test suite

Various tweaks to make the test suite cleaner and more efficient:

- Replace use of "re" module with "pyparsing" in tests (but not base.py)
- Make test_mbox_cve only check for CVE tags in the commit if the added
  patch has them
- Make test_mbox_cve SKIP instead of PASS if there's no CVE tag
- Simplify the bugzilla tag checking test now that pyparsing is used
- Modify the selftest script to correctly parse the new result output
