modules/compose: set default layers
In case some code path creates module contexts and renders without applying settings, it's important to ensure there are defaults. As-is this would have crashed compose because compose_layers would have been NULL, and compose_create_context() assumed compose_layers always contained something useful. Montage would have been an example of this, though for other reasons montage has had compose disabled so I don't think anything currently would have triggered this.
