nvc0: enable GL 4.3 on gm107+

Although, arb_shader_image_load_store-atomicity will most likely
hang your box, I think it's now quite reasonable to enable GL 4.3
on Maxwell/Pascal GPUs. I suspect that test to be wrong because
it doesn't even work on the NVIDIA blob.

I have tested a bunch of benchmarks (UE4 demos) and real games
like Shadow of Mordor and they all work fine.
