utils: wrap-program: Refuse to wrap .X-real files.

Browse Source 
* guix/build/utils.scm (wrap-program): Error if wrap-program was
mistakenly passed a .X-real file. This prevents and forces us to fix
cases where a double wrapped ..X-real-real file is created, such as can
be seen with: "find /gnu/ -iname '.*-real-real'".
