[M140] [rustypng] Discard profiles with invalid gamma

Original change's description:
> [rustypng] Discard profiles with invalid gamma
> 
> Unlike libpng (png_get_gAMA_fixed), image-rs does not validate the gamma
> and can return an invalid value of zero. In that case, we should ignore
> the profile and not attempt the color transform.
> 
> Add an explicit check to match blink/libpng semantics.
