bump Java compatibility level to 1.6, minimum supported by Java 9 (bug #51803)

* scripts/java/module.mk (%.class): Compile Java with -source 1.6 -target 1.6.
* ov-java.cc (octave::JVMArgs::JVMArgs, initialize_jvm, thread_jni_env): Use
JNI_VERSION_1_6 to initialize the JVM.  Thanks to Ernst Reissner for the
suggestion.
