Multiple places coordinate to 'know' where lua scripts are installed. Knock this down to being formally defined (and overridable) in exactly one spot, defs.mk, and spread the knowledge to loaders and liblua alike. A future commit will expose this to lua as loader.lua_path, so it can build absolute paths to lua scripts as needed. MFC after: 1 week
