[FIX] tests: test support for modules without `__init__.py`

Now that a test exists to enforce `__init__.py` in odoo module, we must
ensure that we keep the feature.

For that reason, a white-list system is added in `test_dunderinit` and a
test is added in order to be sure that a module without `__init__.py` can
be exists.

This this is made of a fake module `test_data_module` without
 `__init__.py` and a test module which ensure the fake module was
installed.
