    build: Fix the Makefile rules for the GSettings schema
    
    @GSETTINGS_RULES@ comes from the GLIB_GSETTINGS M4 macro shipped by
    GLib in gsettings.m4. It's unrelated to intltool and should be retained
    as long as Makefiles are being used.
    
    Secondly, unlike desktop and appdata files, the translations for
    GSettings schemas are not merged back during the build. The
    translatable strings are extracted during the build, but the
    translations are fetched at runtime. This is similar to how it works
    for source code. Therefore, there is no need for the *.gschema.xml.in
    to *.gschema.xml indirection. Note that this was already not necessary
    with intltool >= 0.50.
