    meson: Use python.dependency() correctly
    
    From https://github.com/mesonbuild/meson/issues/6470:
    
    > So, to further clarify, passing an argument to
    > py_installation.dependency() should be an error, since this method
    > will only ever return a python dependency (for embedding python
    > itself, etc.) and not dbusmock or anything else.
