rtc: Include segment q for variance thresholds

For variance based partitioning: the variance
thresholds are based on the qp for that superblock.
If the superblock has non-zero segment, use the
segment qp for setting the variance thresholds.

bdrate gains for nonrd_pick_mode (speed >= 7),
On rtc set:
speed 7: ~1.7% avg, several clips over 2%, max 7%.
speed 8: ~0.7% avg, max 6%.
