Instruct pip to use distutils
-----------------------------
The current version of pip uses distutils on Python < 3.10,
so this should change nothing,
but future versions of pip may theoretically change that.
Instruct pypa/distutils to add /local/ addition to prefix
---------------------------------------------------------
Needed for setuptools 60+ installed/upgraded by pip or when we update it in rawhide.
Setuptools 60+ uses bundled pypa/distutils instead of the standard library distutils.
