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.
