swr: only broadcast color0 value, not all color values
The way that dual-source blending is described for GLES2 is very odd, and we end up with a shader that both has this property set *and* has a color1 value to be used as the second source. While changing the state tracker is an option, it seems more reliable to verify that the broadcast is only done on color0.
