🐛 Auto-landfill places landfill unnecessarily

[lisa]

Config:

Factorio 1.1.102, Mod version 0.27.3

Reproduction steps:

1. Create a new game
2. Create a new stage
3. For the auto-selected stage, go to Blueprints -> Settings: Default, enable "Auto-landfill"
4. For the auto-selected stage, go to Blueprints -> Export, select "Get blueprint for current stage"
5. Observe that four tiles of landfill is placed under the player (perhaps more if the player moved)

The expected behaviour is that landfill is only placed under entities, not out in the general area. This can get out of hand for large bases where normal "blank space" would be covered in landfill.
