Marked test as flaky in https://trac.webkit.org/changeset/263701/webkit to speed up iOS EWS. Antoine, would you please take a look at this?

Sadly I'm not very surprised that this test proved to be flaky, although I tried my best for it not to be! Testing this code change is tricky as it's about the behavior of accelerated animations which can only be tested with a ref test of something moving, so pretttttty hard. I'll take a look soon.
