RFR: 8326127: JFR: Add SafepointCleanupTask to hardToTestEvents of TestLookForUntestedEvents

Mon Feb 19 07:03:02 UTC 2024

Greetings,

[JDK-8322630](https://bugs.openjdk.org/browse/JDK-8322630) made the `EventSafepointCleanupTask` hard to test. We'd better move it to hardToTestEvents of TestLookForUntestedEvents instead of commenting out it.
