Revert "Increase the timeout for criteria check"

This reverts commit 3f46dedb.

Reason for revert: The test is still flaky

Original change's description:
> Increase the timeout for criteria check
> 
> From previous enabled test run,
> https://test-results.appspot.com/dashboards/flakiness_dashboard.html#testType=content_shell_test_apk&tests=ClipboardTest%23testCopyDocumentFragment
> It seems most of failure happened on slow devices, like x86.
> So increase the timeout for CriteriaHelper.pollUiThread().
