Add an small per-MB cost penalty for lowres
Helps avoid VBV predictors going nuts with very low-cost MBs.
One particular case this fixes is zero-cost MBs: adaptive quantization decreases the QP a lot, but (before this patch), no cost penalty gets factored in for this, because anything times zero is zero.
