RFR: 8311222: strace004 can fail due to unexpected stack length after JDK-8309408

[Leonid Mesnik]

The [JDK-8309408](https://bugs.openjdk.org/browse/JDK-8309408) introduced sleepNanos and the tests expected stack is updated.
The "jdk.internal.event.ThreadSleepEvent.<init>" was added just because I hit this issue while testing fix.
