Rename JDK system dep to JNI

JNI is a more apt name because it currently only supports the JNI. I
also believe that CMake uses the terminology JNI here as well.

JNI is currently the only way to interact with the JVM through native
code, but there is a project called "Project Panama" which aims to be
another way for native code to interact with the JVM.
