Dirt floors can be constructed on non soil terrain

[PatrikLundell]

Describe the bug

Dirt floors can be constructed on any location where a floor can be constructed, despite it not being a constructed floor, but rather adjustment of pre existing dirt.

Steps to reproduce

1. Walk up the ramp to exit the cellar.
2. Walk up the ladder at the northern side of the northern shack.
3. Build a dirt floor on the roof using the construction menu.
4. See that a dirt floor is now present on the roof.

Expected behavior

Dirt floors should only be possible to make on terrain that's fundamentally soil (i.e. dirt, grass, etc., with the "etc." being up for some debate, due to sand, clay, mud, etc.).

Additional context

I tried to address it using the recently introduced ability to have a list of pre terrain in the dirt floor construction definition, but that failed due to this:
DEBUG : get_build_reqs_for_furn_ter_ids tried to get reqs for constr_dirtfloor which has multiple pre_terrain

FUNCTION : operator ()
FILE : C:\Cataclysm-DDA\src\construction.cpp
LINE : 2587
VERSION : 0.G-13932-gdca38e584e-dirty
so it seems a pre terrain list only is supported for the DECORATE category.
