It looks like the test is just slow. Updated the expectation to slow to see if this stops the timeouts : https://trac.webkit.org/changeset/284274/webkit

The test seems to be still timing out on debug after marked slow. It usually takes 120 ~ 151 seconds to pass on debug, but shows up as timeout when it takes 154+ seconds.

I was not able to reproduce the timeout locally on iOS 15 sim using run-webkit-tests imported/w3c/web-platform-tests/WebCryptoAPI/derive_bits_keys/pbkdf2.https.any.worker.html --iterations 50 --exit-after-n-crashes-or-timeouts 1 --ios-simulator --debug
