[AIX jdk20] : two serviceability/jvmti/ tests got error message `Could not find Agent_OnLoad function in the agent library`

Got

```
Error occurred during initialization of VM
Could not find Agent_OnLoad function in the agent library: GetOwnedMonitorStackDepthInfoWithEATest | IterateHeapWithEscapeAnalysisEnabled

```

Start with the two named tests: serviceability/jvmti/GetOwnedMonitorStackDepthInfo/GetOwnedMonitorStackDepthInfoWithEATest.java and serviceability/jvmti/Heap/IterateHeapWithEscapeAnalysisEnabled.java, then inspect the linked AIX CI reports. Determine why each test's agent library lacks Agent_OnLoad on AIX; done means both tests run successfully without the initialization error.
