Reduce baseline inter enumerator in av1_rc_bits_per_mb()

Reduce the baseline inter enumerator used to estimate
bits per MB in the rate control heuristics. This value is now
separate from the calculation used to estimate maxq in the
two pass code.

The impact of this change will be to slightly lower the initial
q estimate for a given target bitrate.

Small metrics gains on all sets (av psnr, ov psnr, ssim, psnr-hvs)
