Biome dust: Revert fix that added dust to mod structures (#7464)

Revert commit 99143f4 and commit
f4ca830.

These commits caused biome dust to be applied even when there was no core
mapgen terrain in a mapchunk column. So the dust, which overgenerates,
then appeared on structures added by mods in 'on_generated', such as
floatlands, asteroids or above-surface realms.
