Updated test expectations to Pass ImageOnlyFail for Debug platform here:

https://trac.webkit.org/changeset/276168/webkit

Test already had expectations set from a prior bug. However, that bug appears to have been closed without actually doing anything. I have related the prior bug here to this bug: 
https://bugs.webkit.org/show_bug.cgi?id=222332

I was able to reproduce the failure at BigSur Release ToT using the following test:

run-webkit-tests compositing/video/video-border-radius-clipping.html --iterations 1000 --child-process=50
