tests: skip docker-py exec exit code test

Temporarily skip the exec run failed exit code test in `docker-py` –
https://github.com/docker/docker-py/blob/a3652028b1ead708bd9191efb286f909ba6c2a49/tests/integration/models_containers_test.py#L356-L363

We can reenable this after the PR fixing the expected exit code in that
test is merged/released/included – docker/docker-py#3290
