    build: install gobject-introspection with MSYS2 when cross-building…
    
    … for Windows.
    
    Though it's useless for actually building the GIR files, we still need
    this package now, for building script-fu with introspection abilities,
    to generate GIMP and GEGL enums.
    See the 2 previous commits for more information.
