bitbake: knotty: import latest python-progressbar

Since we're going to make some minor extensions to it, it makes sense to
bring in the latest version of python-progressbar. Its structure has
changed a little but the API hasn't; however we do need to ensure our
overridden _needs_update() function's signature in BBProgress() matches
properly.
