    Fixing hang in get_module_qualname_from_path

    This commit fixes a possible hang in the get_module_qualname...
    function. When running against a '.' target, the while statement
    would loop forever looking for a head of '/', when all it would
    ever find was '.'. Now either option is enough to break the loop.

    A head of '.' already indicates we're as far down as we can get
    since there is no non-file path left.
