python-setuptools: re-introduce patch from python3

Browse Source 
When Python3 was updated via commit 97a92f2e7 , distutils was
disappeared from Python3 and moved to setuptools.
So that patch should have moved here as well.

This should fix all packages which still use the 'build_ext'
module from setuptools.

Subject: [PATCH] Adjust library/header paths for cross-compilation
When cross-compiling third-party extensions, the get_python_inc() or
get_python_lib() can be called, to return the path to headers or
libraries. However, they use the sys.prefix of the host Python, which
returns incorrect paths when cross-compiling (paths pointing to host
headers and libraries).
In order to fix this, we introduce the _python_sysroot, _python_prefix
and _python_exec_prefix variables, that allow to override these
values, and get correct header/library paths when cross-compiling
third-party Python modules.
