Attempt to deflake video-layer-crash.html.

This makes the test wait for layout and paint, instead of finishing the test as
soon as the seeked event is seen. Currently the Retina bot flakily produces the
frame previous to the one that is expected.

Revert of Attempt to deflake video-layer-crash.html. (patchset #1 id:1 of https://codereview.chromium.org/2053793002/ )

Reason for revert:
Didn't deflake -- and there should be a synchronous layout/paint before pixel dump anyhow.

Replace expected pixel result for video-layer-crash.html on Mac Retina.

It looks like this was already flaky before my patch, but the rebaseline bot
had the misfortune of grabbing a bad expectation. If so, hopefully committing
the good expectation will fix things.

Remove [ Failure Pass ] expectation for video-layer-crash.html.

It was mildly flaky before my patch, so in all likelihood this trouble was
caused only by the rebaseline bot picking a bad run on Retina (there are
flaky-but-pass-on-retry failures before and after my original patch on the
flakiness dashboard, and it's not obvious why this test is flaky).

It worked! This test is no more flaky than it was before.

(I wish this test weren't flaky at all, but I don't know the media pipeline well enough to know what's up here.)
