Avoid preloader-induced test flakiness.
If a preload request for <img> preload fails, the request will be retried
on parsing the element as per normal. This might result in more than
one request for the same resource, and consequently more than one console
error message might be output.
For img-crossorigin-no-credentials-prompt.html, avoid having the preloader
kick in by not relying on an external script.
