wic: rename kickstarter.py -> ksparser.py

kickstarter.py was not the best name for this module as previously
there was a directory with the same name in scripts/lib/wic/.
All files were removed from it, but .pyc files could still stay there
causing imports from wic.kickstart to fail with
ImportError: cannot import name KickStart.
