encoder: h264: improve automatic bitrate calculation.

For non "Constant-QP" modes, we could provide more reasonable heuristics
for the target bitrate. In general, 48 bits per macroblock with all the
useful coding tools enable looks safe enough. Then, this rate is raised
by +10% to +15% for each coding tool that is disabled.
