[gnome-continuous-yocto/gnomeostree-3.28-rocko: 6010/8267] python3: Use _sysconfigdata.py to initialize distutils.sysconfig

[Emmanuele Bassi <ebassi src gnome org>]

commit 0862df262d7bd4b016a3fcb8a2f2fff7e0cd957b
Author: Li Zhou <li zhou windriver com>
Date:   Sat May 27 17:46:15 2017 +0800

    python3: Use _sysconfigdata.py to initialize distutils.sysconfig
    
    Porting patch from
    <https://github.com/python/cpython/commit/409482251b06fe75c4ee56e85ffbb4b23d934159>
    to use _sysconfigdata.py to initialize distutils.sysconfig.
    
    This patch makes that distutils.sysconfig doesn't need config-*/Makefile
    in libdir any more. Next we can move it from python3-misc to python3-dev
    package.
