patch 9.0.1794: autoconf: not correctly detecing include dirs
Problem: autoconf: not correctly detecing include dirs
Solution: make use of python3 to generate includedirs
configure: Python3: Use sysconfig for -I
It seems better to use tools provided by Python for determining the
include directories, rather than construct them "manually".
Current system is broken when using virtual environments for python
3.11.4. It used to work before, but now it detects a incorrect value
for `-I`.
It would probably make sense to switch to a similar logic for lib
folders, that is for the `-l` switch. There are also
`sysconfig.get_config_h_filename()` and
`sysconfig.get_makefile_filename()`, that could replace more Python
specific logic in the current `configure{.ac,}`.
sysconfig provides the necessary tools since Python 2.7.
