8272966: test/jdk/java/awt/Robot/FlushCurrentEvent.java fails by timeout

[mrserb]

The test case backported by the JDK-8267722 is too strict for jdk11. It uses the Robot.delay() method which is synchronised in jdk11 and this caused a deadlock.

Main thread: synchronized robot.waitForIdle() - > trying to synchronously execute the code on EDT
EDT: trying to call synchronized Robot.delay()

The synchronized keyword was removed by the JDK-8210231 in JDK15 and it cannot be backported due to compatibility reasons.

The solution is to relax this part of the test which does not affect its ability to verify the fix for JDK-8196100
