[XEN PATCH v3 2/4] tools: convert setup.py to use setuptools if available

[Javi Merino <javi.merino@xxxxxxxxx>]

From: Marek Marczykowski-Górecki <marmarek@xxxxxxxxxxxxxxxxxxxxxx>

Python distutils is deprecated and is going to be removed in Python
3.12. Add support for setuptools.

Setuptools in Python 3.11 complains:

  SetuptoolsDeprecationWarning: setup.py install is deprecated. Use build and 
pip and other standards-based tools.

Keep using setup.py anyway to build the C extension.
