Delete unused "six" from mac app

[jdemeyer]

There are two reasons why we should not have a copy of six in src/mac-app/tools/createDSStore/six.py:

1. six is not actually used by the Mac App.

2. We already ship six with Sage.

This makes sense to me but I don't have time right now to really test it out: build the app and run it. I am not planning to test with https://github.com/sagemath/binary-pkg.
