Properly implement PEP 302 in the module_loading module.  For unknown reasons this doesn't actually raise an error under CPython, but PyPy does, and the currently implementation is clearly in violation of the PEP, which states that finder.find_module's second argument is either None or package.__path__ and imp.find_module whose second argument should be either None or a list of paths.
