Corrected libmix image encoder's max coded size computing formula for small images on max quality.

BZ: 170493

Issue: the current max JPEG coded size computing
formula fit large images, but its output was too small
if working on small images (320*240/640*480 on 100).

Solution: Corrected that formula.
