rtc-screen: Adjust condition on intra for flat blocks

For spatially flat blocks in screen mode:
in addition to color, add condition on block size
to force intra check (force check for large blocks),
when superblock has motion.

Removes artifacts in 4K test clip with color motion.

rtc_screen speed 10: avg. bdrate gain of:-0.33/-0.35/-0.57
2 clips ~1.25% gain, several are bit-exact.
No speed change.
