python-backports-init: Add helper class and recipe

Recipes that install in the backports namespace have
a tendency to conflict in the installation of
.../site-packages/backports/__init__.py

Add a class and recipe to help avoid the conflict.

Modify recipes that are affected:
  - python-backports-functools-lru-cache
  - python-backports-ssl
  - python-configparser
