After recent changes to the Docker image, all hell broke loose and the CI started failing. This patch marks a few tests as unsupported until we can figure out what the issues are and fix them. In the future, it would be ideal if the nodes could pick up the Dockerfile present in the revision being tested, which would allow us to test changes to the Dockerfile in the CI, like we do for all other code changes.
