test: improve known_issues/test-vm-timeout-escape-queuemicrotask

Improve known_issues/test-vm-timeout-escape-queuemicrotask to mitigate CI failures on ubuntu1604-arm64. Failures are due to a race condition. Use `common.platformTimeout()` to help, adjust timeout to make sure `queueMicrotasks()` has a chance to run, and improve error message.
