Without arguing for or against BT.601 behaviour...

nvenc should behave the same as libx264, or any other video encoder, if
this patch makes it do that, then it should be applied.

If bt601 needs special handling not yet present in avcodec, it should be
implemented in such a way that all encoders can benefit from it.
