I did a successful test build, but I don't currently have a system with libav59 libraries to test it on.

The fix looks good to me with one exception. You also need to add an entry for `"avplugin-ffmpeg-59"` in the [NativeMediaManager constructor](https://github.com/openjdk/jfx/blob/bb4cead00e952484896191ca0e41f1608ae5b41e/modules/javafx.media/src/main/java/com/sun/media/jfxmediaimpl/NativeMediaManager.java#L127).
