tests: nydus: Skip tests when using dragonball

[fidencio]

When updating nydus to 2.2.3 and nydus-snapshotter to 0.12.0, some work will be needed on dragonball side as the nydus tests are failing there with the following error:

When we get this resolved and re-enable the test we'll need to be aware to remove the skip in kata-containers tests (introduced in kata-containers/kata-containers@aea39f8) as well
