uninstall: use --record with setup.py, v2

--record option allows us to keep track of files that are being
installed by writing them to specified file. We can than use that
file to do proper cleanup on uninstall.

v2, drop -r, as we shouldn't really care about dirs, because
    setup.py doesn't report them to us.
