Ensure native libraries are loaded properly if running on OSGi

System.loadLibrary works properly in a real OSGi context in
combination with Bundle-NativeCode manifest headers. The hacky
JNIUtils with reflection and absolute paths is broken on newer
Java versions unless add-opens is added. We don't need that.
