python: add capability to install python packages for the host

Browse source 
Some python packages (e.g. cffi) compile one or more shared libraries
as part of their setup process. When these packages are setup
dependencies of other packages (e.g. cryptography), these packages (and
their shared libraries) will need to be loaded on the host system.

This adds a makefile, similar to python-package.mk, to simplify
installing python packages on the host.
