Subject: [PATCH] pythonPackages.python-mapnik: Fix build

There were two things to fix:
- Boost started shipping libboost_python.so as libboost_python{Major}{Minor}
- Make sure that mapnik and boost link to the correct version of python.

(cherry picked from commit be6451e0205ecf779986128b0f7e0171cb64803a)
