rtc: Enable the use of golden ref for speed < 7

The golden ref was disabled to avoid encoder speed decrease in
https://aomedia-review.googlesource.com/c/aom/+/142041
This was re-evaluated for rt speed 5 and 6. The coding gain was
significant and outweighed the speed drop. Thus it was enabled.
Here were borg test results.

speed 5:
rtc_derf:  -3.041    -3.112    -3.377    -11.518

speed 6:
