[PATCH nft 2/2] py: remove setup.py integration with autotools

[Pablo Neira Ayuso <pablo@netfilter.org>]

With Python distutils and setuptools going deprecated, remove
integration with autotools. This integration is causing issues
in modern environments.

Note that setup.py is still left in place under the py/ folder.

Update INSTALL file to refer to Python support and setup.py.
