python3: fix create_manifest to handle pycache folders
We have a couple of python modules that contain folders themselves,
for that reason they also contain a __pycache__ folder inside those
directories, since we include the whole folder in the manifest, the
pycache directories end up with the files and not the cache files.
This patch catches that and adds the directories to the correct
structure.
