Depal from dynamic CLUT: When detecting bounds, be more conservative.

Followup to hrydgard#16188 .

Further fixes the lens flare.

It confused me before that there are two sections of the track on
Sunset Drive where the sun is visible, but only on the second is the
lens flare sprite actually shown, which is rather weird.

Verified that exactly the same thing happens on hardware, so it's not a
an emulation problem! Rather seems like a glitch in the game itself.
