Fix showing DeprecationWarnings for functional tests

[cdce8p]

Description

The recwarn fixture for test_functional prevents all DeprecationWarnings from showing up which aren't triggered at import. Noticed while working on a DeprecationWarning for pylint-dev/astroid#1389.

The previous code was added in e37bf8c.

Thank you for the fix, that was my bad !

@Pierre-Sassoulas Seems like you accidentally dismissed the approval.

(I'm planning on creating a standalone pylint testutil package that would be properly tested, I don't dare to tell when 😄 I need adminship in pycka or a pylint organisation first)

It seems I'm able to create a new repo in the PyCQA org. You should also be able to already.

Just to clarify, this is just a helper package for running functional tests? The tests themself will stay here?
(That's what I would suggest, at least.)

It would be the current content of pylint.testutil, we'd make it an optional install later on (so pylint is lighter for everyone, but lib developer can still use it without too much change in their requirements). The test we'd move would be the one to test the testutil themselves (tests.testutils https://github.com/PyCQA/pylint/tree/main/tests/testutils).
