gdb/python-config: replace deprecated distutils.sysconfig

Browse Source 
When running the gdb/configure script on ubuntu 22.04 with
python-3.10.4, I see:

    checking for python... yes

The distutils module is deprecated as per the PEP 632[1] and will be
removed in python-3.12.

This patch migrates gdb/python/python-config.py from distutils.sysconfig
to the sysconfig module[2].

The sysconfig module has has been introduced in the standard library in
python 3.2.  Given that support for python < 3.2 has been removed by
edae3fd6600f: "gdb/python: remove Python 2 support", this patch does not
need to support both implementations for backward compatibility.

Tested on ubuntu-22.04 and ubuntu 20.04.
