Refine init value of rate_correction_factors

rate_correction_factors used to map QP to bitrate.
As observed, the init value for the first alt ref
is always too large, which cause it re-encode
multiple times.

For encoder, about 2.6% faster shows by encoding 20 frame
of BasketballDrill_832x480_50.y4m target 800kbps.
