Frederik Rietdijk 3b83c23012 python.pkgs.bootstrapped-pip: upgrade pkg_resources, fixes #26392
pip 9.0.1 vendors a version of setuptools/pkg_resources which has been
fixed in setuptools/pkg_resources but not yet in pip. Because we're now
facing this issue with nox, we update pkg_resources to the version we
also have in setuptools. Let's cross our fingers this will work without
breaking other stuff.
