Dmitry Kalinkin 8fa36fc8a1 python: provide hasCxxDistutils attribute for pythonPackages.numpy
Patching numpy.distutils used to be required for pythonPackages.cython
to build on darwin. It was later accidentally disabled during one of the
refactorings, but that did not break cython. This change reinstantiates
the patch. It still applies, so it should be low maintenance and it can
still be useful.
