Suppress a w3c test for Shadow DOM.

Suppress a w3c test for Shadow DOM.

This is a pre-requirement patch to land https://codereview.chromium.org/137993003/.

I am going to follow the following procedure:

1. Suppress a w3c test which would fail if I land https://codereview.chromium.org/137993003/
2. Land https://codereview.chromium.org/137993003/
3. Update the w3c test and upstream it to the w3c repository
4. Wait until the test is imported to blink.
5. Remove the suppression.
