make bddeb work with python3 or python2

painful, and not perfect, but at this point the output builds
on a vivid system python2 (bddeb --python2) or python3.

 * remove use of cheetah by bddeb in favor of builtin renderer
 * add '--python2' flag to bddeb and knowledge of python 2 and python3
   package names.
 * read-dependencies can now read test-requirements also.
 * differenciate from build-requirements and runtime requirements.
