Added a Mesa task. RAOF has suggested we should just fix Mesa. When
asking for RGBA of 8880 it should provide at least one EGLConfig that is
8880 instead of always 8888.

Bug description:
  [regression] Fullscreen GL apps don't get bypassed any more.

  As you can see in compositor report from any of our demo servers:
  [1438572052.621854] compositor: Display 0x7faea4306fa0 averaged 60.537 FPS, 0.506 ms/frame, latency 15.669 ms, 61 frames over 1.007 sec, 0% bypassed
  [1438572053.622668] compositor: Display 0x7faea4306fa0 averaged 59.950 FPS, 0.551 ms/frame, latency 15.814 ms, 60 frames over 1.000 sec, 0% bypassed
  [1438572054.623370] compositor: Display 0x7faea4306fa0 averaged 59.958 FPS, 0.613 ms/frame, latency 15.721 ms, 60 frames over 1.000 sec, 0% bypassed

  I think this is only "medium" though, because it's a transparent
  optimization so its absence is very hard to notice in most cases.
