GPULightmapper: process rays to sky in all bounces as active
Before this change only rays to the sky (RAY_MISS) in the first bounce were processed as active rays. This caused artifacts, areas were too light, when more than one bounce were processed. Now rays to the sky are processed as active rays for all bounces.
