Switch SL4N over to using Android.bp (3/3)

Due to the move to using mostly header libs for the AVRCP changes SL4N
couldn't find references to certain files without having to include a
large number of include directorys. Swapping the Makefile to Android.bp
makes this much easier to handle.

Bug: 68854188
Test: Compile and see that the application exists where it should
