Increase Minimum KF boost.

This increase in the minimum KF boost impacts only very complex clips
and in practice mainly impacts smaller image formats.

Using 150 frames VBR over typical YT data rates their was only a very small
effect for the midres and hd res sets.

For the Lowres data set the results were as follows (% -ve = better)
-0.037, -0.031, -0.112, -0.043 (av psnr, overal psnr, ssim, psnr-hvs)

Even on this set most clips see no change. The largest change is Husky
(-1.093, -0.772, -2.305, -1.363)
