remove fix-products-paths that is no longer required with recent ERP5.

to migrate other repositories containing product/ but no Products/, you can do like the following :

* make a symlink Products -> product
* git add Products && git commit

if the repository has no product/__init__.py, you can copy from erp5/product/__init__.py.
