licensing: "Python-2.0" is fine in Fedora
    
    The license is listed on fedora's list of "Good" licenses:
    https://fedoraproject.org/wiki/Licensing:Main#Good_Licenses.
    It is called "Python" and the notes link to
    https://docs.python.org/2/license.html.
    
    https://spdx.org/licenses/Python-2.0.html provides the exact same text
    as https://docs.python.org/2/license.html. Thus SPDX's "Python-2.0" is
    the same as our "Python".
    
    Fixes #121.
