[XEN PATCH v2 2/5] tools: convert setup.py to use setuptools

[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. Migrate to 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 C extension.
