Original change's description:
> Enable camera blob stream when needed
> 
> Since blob stream needs higher resolution, it causes higher cpu loading
> to require higher resolution and resize to smaller resolution.
> In hangout app, we don't need blob stream. Enabling blob stream when
> needed can save a lot of cpu usage.
> 
> BUG=b:114676133
> TEST=manually test in apprtc and CCA. make sure picture taking still
> works in CCA.
