These two tests also need `/native` keyword.

- Test test/jdk/java/lang/Thread/virtual/ThreadPollOnYield.java do not report test failed or error when missing load the native shared libary. So I add a check to make sure that the first virtual of this test run normally.

The original test output from jfr file shows below:

- Test test/jdk/java/lang/Thread/virtual/Starvation.java execute over 120 seconds on my local environment. So I add `timeout=200` also.


elapsed time (seconds): 121.41
