python: move to Git formatted patches

Now that the cpython project has a nice Github repository, with tags,
it's much nicer to handle the stack of Python patches with Git. The
python3 package patches had already been converted, but not the python
package patches. Therefore, this commit does the move.

There is no functional change, only reformatting of the patches.
