>>  Test `jdk/jfr/event/oldobject/TestShenandoah.java` run timed out after [JDK-8279016](https://bugs.openjdk.org/browse/JDK-8279016), because of infinite loop of `Could not find leaking object, retrying...`
>> In [JDK-8279016](https://bugs.openjdk.org/browse/JDK-8279016), this test has been Problemlisted by [ProblemList-shenandoah.txt
>> ](https://github.com/openjdk/jdk/blame/master/test/jdk/ProblemList-shenandoah.txt#L52), because of the LeakProfiler tests not suitable for run with `-XX:+UseShenandoahGC` after [JDK-8279016](https://bugs.openjdk.org/browse/JDK-8279016).
>> But in the VM option `-XX:+UseShenandoahGC` set inside the test tag cause the Problemlist mechanism will not take effect. The problemlist only take effect when the VM option set from command line such as `make TEST JTREG="JAVA_OPTIONS=-XX:+UseShenandoahGC"`.
>> So in this PR move Problemlist entry `jdk/jfr/event/oldobject/TestShenandoah.java` from `test/jdk/ProblemList-shenandoah.txt` to `test/jdk/ProblemList.txt` to make this test could by excluded normally.
>> The other optional solution is delete the VM option `-XX:+UseShenandoahGC` in test file to make test run passed. After [JDK-8342951](https://bugs.openjdk.org/browse/JDK-8342951) has been resolved, the change should be backouted. This PR choice the previous one solution.

>> Test-fix only, no risk.
