leocad: enable povray support

Browse source 
To make povray work, the configurability of its path needs to be
disabled, as otherwise the povray binary's absolute path would be stored
in the leocad profile, breaking it as soon as povray is updated with a
changed store path.

A patch disables the configurability and makes leocad call a hardcoded
path pointing to the povray binary provided through
propagatedBuildInputs

Subject: [PATCH] Don't use configurable POV-ray path.
Once the POV-ray path is configurable, it'll be written to the LeoCAD
profile, which will break upon the next update of POV-ray which will
have a different Nix store path.
