Update Camera.cpp

camdist multiplier is consitently between 1 and 1.4 on 16:9 aspect ratio
On ultrawide, the cam dist multiplier jumps to anywhere between 2 and 3
The preferred distance generator for car objects is the cam dist multiplier * 120. Which puts cars that it's trying to generate outside of the allowed gen/draw distance for new car objects when on ultrawide. This means no new cars can spawn.
This change caps the scaling for the generation distance a bit above what it would be for 16:9 and does not affect the LOD multiplier.
