The test doesn't apply anymore.
Conversation at https://github.com/moby/moby/issues/38587 suggests that
one of the 2 failures we observed might be fixed.
As for the second one, seems like some work related to it was merged,
but not in the version 18.09.9, so I think we'll have to re-introduce
Let's drop it for now and see what happens.
