Subject: [PATCH] pythonPackages.yowsup: disable python2 build

I'm not exactly sure why, but it seems as the python2 build
of yowsup is breaking.
see https://github.com/tgalal/yowsup/issues/2325

It seems to be recommended to use python3 for building and disable
the usage of python2 which fixed the build.
