package: add python3 support in the package infrastructure

Browse Source 
This commit improves the Python package infrastructure to allow Python
packages to be built with Python 3. The changes are fairly simple:

 * Use either PYTHON_PATH or PYTHON3_PATH as the PYTHONPATH depending
   on which Python is used.

 * Depend on host-python or host-python3 and python or python3
   depending on which Python is used.
