RFR: 8300295: [AIX] TestDaemonDestroy fails due to !is_primordial_thread assertion [v9]

[Varada M]

> The assertion failure with exit value 134 for the test TestDaemonDestroy.java is because when the JNI_CreateJavaVM is being called by main thread on AIX it prevents the jvm creation on the primordial thread on AIX. This is solved in such a way that when JNI_CreateJavaVM is called it runs in pthread thus enabling the creation of jvm.

> JBS issue for this test : [JDK-8300295](https://bugs.openjdk.org/browse/JDK-8300295)
