Fix ModuleNotFoundError for _distutils/util.py:byte_compile

[kfollesdal]

Summary of changes

Solve ModuleNotfoundError 'No module named 'distutils' for function _distutils/util.py:byte_compile. By adding import setuptools to the script in byte_complie, distutils will be available.

The python package thrift is broken for python 3.12 in nixpkgs, since distutils was removed in python 3.12. The thrift python package use setuptools/distutils to build.

The build process use the function _distutils/util.py:byte_compile, that run a python script in a subprocess. Problem is that we get error:

       >   File "/build/tmpgob9mq6_.py", line 1, in <module>
       >     from distutils.util import byte_compile
       > ModuleNotFoundError: No module named 'distutils'

when it try to build. Problem is that in the subprocess the setuptool is not imported and therefore are distutils not available.

This PR solve the problem by import setuptools first in the script.

Close since duplicate of #4229

Found a solutions by modify PYTHONPATH before build:

DISTUTILS=$(mktemp -d)
ln -s ${setuptools}/${python.sitePackages}/setuptools/_distutils "$DISTUTILS/distutils"
PYTHONPATH="$PYTHONPATH:$DISTUTILS"
