rtc: Enable RTC reference strucutre for speed >= 6

Enable set_reference_structure for 1 pass RTC, for
speed >= 6. This bypasses the internal structure,
but the behavior explicitly set by the flag
set_reference_structure is very similar (mainly
fixes the golden update to be what was intended for
RTC, and provides flexibility for future adjustments).

bdrate gains on all clips for rtc_derf set:
speed 7: avg. ~1.1%, max ~4.8, a few clips over 3%.
speed 6: avg. ~0.35, max ~1.45.

No speed/fps change observed.
