[meta-python2][PATCH] python-setuptools: copy patch from oe-core

[Tim Orling <ticotimo@gmail.com>]

The following patch is needed for python-setuptools-native:
0001-conditionally-do-not-fetch-code-by-easy_install.patch

While currently this is duplication of the same patch in oe-core,
there is no guarantee that the patch will continue to stay in sync
for py2, so copy the known working patch now.
