[FIX] base: allow patching of config.options for 3.11

Since python/cpython#18544, unittest mock is not able to properly find
the "odoo.tools.config".

When trying to patch the `options` dictionnary, it leads to
`AttributeError: module 'odoo.tools.config' has no attribute 'options'`

In order to have the tests
working in python <= 3.11, we have to import the config module and patch
the options in place.
