[rust png] De-flake toBlob-cross-realm-callback-report-exception test.

Before this CL, the test assumed that frames[1].onerror will be called
within 25ms. It seems that after switching to the Rust PNG encoder this
doesn't always happen. So after this CL:

1. The test will wait until at least one frames[i].onerror happens
   (with a timeout of 3s). This is expected to make the test more
   robust and less flaky.
2. Only afterward the test will wait an additional 25ms to see if
   unexpectedly any other onerror has fired. This part may continue
   to be flaky, but this CL doesn't make this worse... :-/
