build-system/glib-or-gtk: Allow specific outputs to be excluded from wrapping. 

* guix/build/glib-or-gtk-build-system.scm (wrap-all-programs): Add
  #:glib-or-gtk-wrap-excluded-outputs parameter and honor it.
* guix/build-system/glib-or-gtk.scm (glib-or-gtk-build): Add
  #:glib-or-gtk-wrap-excluded-outputs parameter and pass it in BUILDER.
* doc/guix.texi (Build Systems): Mention it.

that appropriately set the @code{XDG_DATA_DIRS} and @code{GTK_PATH}

It is possible to exclude specific package outputs from that wrapping
process by listing their names in the
@code{#:glib-or-gtk-wrap-excluded-outputs} parameter. This is useful
when an output is known not to contain any GLib or GTK+ binaries, and
where wrapping would gratuitously add a dependency of that output on
GLib and GTK+.
