When the program binding changes, we set the descriptor sets binding
dirty bit if the program had any textures, UBOs, SSBOs, images or atomic
counters.  The check for default uniforms was missing.  So if the two
programs had no resources and were only using default uniforms, then
drawing with one after the other didn't update the descriptor set
binding of the default uniforms for the second draw.
