- update default strip data to make the initrd a bit smaller
  * remove /usr/share/grub2/backgrounds
  * remove /usr/share/kbd
  * remove /usr/lib/rpm

  setup is requested like it is the case with EFI capable
  hybrid iso's. They use isolinux/gfxboot for the bios boot
  case and grub2/grub2-branding for the EFI boot. Thus the
  branding data needs to be handled for both and not only
  one loader
