python distutils stdlib module deprecation

[emollier]

Hi,

When wrapping py2bit 0.3.2 for Debian sid, lintian flagged a use of distutils in setup.py. Looking at PEP 632, it is deprecated since Python 3.10, and the contemporary use for importing sysconfig is to use the bare module. I prepared a patch to implement the approach recommended by the PEP, but perhaps a longer term approach would be to move to pyproject.toml instead:

--- python-py2bit.orig/setup.py
+++ python-py2bit/setup.py
@@ -1,6 +1,6 @@
 #!/usr/bin/env python
 from setuptools import setup, Extension, find_packages
-from distutils import sysconfig
+import sysconfig
 import subprocess
 import glob
 import sys

Feel free to use whichever approach seems best fit.

In hope this helps,
Étienne.
