app/internal/window: [Android] remove JNI_OnLoad JNI callback

Browse Source 
There can only be one JNI_OnLoad callback per JNI library, and the
Gio program may need it for its own purposes.

Gio only used JNI_OnLoad for explicitly registering native methods. Switch
to implicit name based registration and get rid of JNI_OnLoad.
