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.
