Revert "Correct the Python_module handling"

    This reverts commits 33671f54b993aac75887647d4c519856137be632 and
    52fdc8e546d57375058ef0a3e6a6797ee4755c24.

    These commits introduce a bug in the generation of python modules:
    shared objects wrap.so have been renamed but __init__.py files still try
    to import them with the old name.
