[IMP] module.py: remove useless pkg_resources jinja hook

The `PackageLoader` jinja's loader purpose is to discover template files
given a python module path. It was necessary to register a special hook
into the import scheme of Odoo to support `import crm`, `import openerp`
and `import openerp.addons` like module path.

Since the support for those old module paths is deprecated since v13 and
the jinja's team shows desire to remove support to `pkg_resource` utils
as highlighted by #50552, it is better to remove it.
