rtc: Somes fixes to nonrd_pickmode, speed >= 7

For spatially flat blocks:
 -reduce intra_cost penalty if best inter mode is
large motion or non-LAST reference
 -forced DC intra to be checked for big blocks

Improves quality for uncovered areas.

Neutral bdrate on rtc_derf set.
No speed change observed on QVGA test clip where
the above change has positive visual effect.
