rtc: Force update of last on gf_update for nonrd

For fast nonrd_pickmode: golden is treated
as secondary reference (with early exits), so
on a GF_UPDATE frame its better to update both
LAST and GOLDEN.

This affects the default/internal behavior of
the reference frames; it does not effect the case
where user supplies the frame flags
(i.e., ext_refresh_frame_flags_pending = 1).

~1.5% average gain in bdrate on rtc set, a few clips
up by 3%.
