build-system/gnu: Add support for non-directory search paths.
Partly fixes <http://bugs.gnu.org/18033>. * guix/build/utils.scm (search-path-as-list): Rename 'sub-directories' parameter to 'files'. Add #:type parameter and honor it. (set-path-environment-variable): Likewise. Pass #:type to 'search-path-as-list'. * guix/packages.scm (search-path-specification->sexp): Add 'directory as the last item of the tuple. * guix/build/gnu-build-system.scm (set-paths): Add 'type' to search-path pattern. Pass #:type to 'set-path-environment-variable'.
