compositing/video/poster.html

Is a flaky timeout on iOS 14 E Simulator wk2.

History: https://results.webkit.org/?suite=layout-tests&test=compositing%2Fvideo%2Fposter.html&platform=ios

No diff. 

stderr: Wait on notifyDone timed out, process WebKitTestRunnerApp pid = 45609

There are also crashes seen on debug. Crash log is very similar to one that's recently fixed here https://bugs.webkit.org/show_bug.cgi?id=228038. Not sure if this crash is the same cause, but I will mark expectations only for timeout since there are no recent crashes. 

I was able to reproduce the timeout both on debug and release on iOS 15 simulator on my local machine using: 

run-webkit-tests --debug --ios-simulator --iterations 500 --exit-after-n-failures 2 --exit-after-n-crashes-or-timeouts 2 compositing/video/poster.html

I was not able to bisect but it seems to be somewhere between r265027 and r266279.

r265027 is the oldest available spade I was able to reproduce the timeout. At r266279 the test was flaky failing instead of timing out: https://bugs.webkit.org/show_bug.cgi?id=215929

Updated expectations. Since I don't see ImageOnlyFailure, which was marked previously, in the recent history, I replaced it with Timeout. https://trac.webkit.org/changeset/280455/webkit
