Android: Cleanup ClassLoaderUtil/LauncherUtil - Using cached parent ClassLoader for SYS-Packages w/ native libs, and non cached child ClassLoader for USR-Packages

Android's Dalvik VM, like a JVM, cannot load a native library from one location by multiple ClassLoader.

Since we don't like to hardcode the system-packages, as it was before, i.e. "com.jogamp.common", "javax.media.opengl",
we need to either copy the libs or use parenting of cached ClassLoader.
The latter is chosen, since it's faster and uses less resources.

- System-packages are passed through from the user 'List<String> LauncherUtil.BaseActivityLauncher::getSysPackages()'
  to the ActivityLauncher, which instantiates the ClassLoader.

- No more hard-reference the system-packages in ClassLoaderUtil ("com.jogamp.common", "javax.media.opengl"),
  just use the new user provided system-packages.

- The system-packages denominate a hash-key for caching, a new ClassLoader is created and mapped
  if it does not yet exist.

- A non-chached user-packages ClassLoader is created using the cached system-packages ClassLoader as it's parent.
