passExtensions.pass-audit: 0.1 -> 1.0.1, refactor

Updates to v1.0.1[1] which supports subdirs and zxcvbn[2]-based
complexity checks. Also, the following things changed:

* Add separate output for man-pages
* Enable test-suite (after adding a patch which mocks the
  `pwnedpasswords.com`).
* Added myself as maintainer.
