Auto roof on "rock" construction results in natural rock roof

[PatrikLundell]

Describe the bug

The various constructed "rock" (in reality stone) terrain are defined to have a roof of t_rock_roof. However, t_rock_roof is described as natural rock, not something you can construct atop a wall made of stones.

Attach save file

N/A. It's JSON definitions.

Steps to reproduce

1. Search the json files for e.g. the definition of t_drystone_wall data/json/furniture_and_terrain/terrain-walls.json).
2. Examine the "roof" element.
3. Locate the definition of "t_rock_roof" and find it's described as natural rock.

Expected behavior

Roofs on top of man made structures should be man made, not magically transformed into natural rock.

I don't know what the appropriate kind of roof for a stone wall to be. It could be one of the roof types already defined, or the ambitious could define a new type of stone roof.
