It removes libjvm.so as a recorded dependency for libExplicitAttach.so by not explicitly link libExplicitAttach.so with libjvm.so at build time. To do that, it also changes libExplicitAttach.c to dynamically lookup the JNI_GetCreatedJavaVMs symbol then invokes the function using the obtained address. The change makes the test to work on both regular 'jdk' image and the 'static-jdk' image.

Based on my understanding, we are converging on the approach to fix just these few tests, and both @dholmes-ora and @AlanBateman are okay with that. So I'm sending out this PR for libExplicitAttach's fix as well.
