vp9 svc: Denoise golden when it's a temporal ref.

Browse Source 
When golden was the inter-layer reference, a block that selected the golden ref
would not be denoised.
But when golden is used as a second temporal reference then we should denoise
blocks that select the golden reference.
This changes allows for that.
