[omx] Avoid hang following jpegs that failed to decode

There's a few instanced of xbmc hanging following a jpeg that failed to decode on GPU:

[rbp] Reduce GPU memory use when limited

Switching from default triple buffered output to double buffered saves 8M with 1080p GUI.
This may slightly reduce framerate, but is likely to be minimal.

Assume if gpu_mem is set below the default 128M that this memory reduction is wanted
