- Add mkinitrd script to add Intel microcode to initrd.

This is needed because microcode driver is built in or gets loaded
  automatically via udev early. Therefore the microcode has to be available
  in initrd already.
  This must not be mixed up with early micorcode loading. This feature will
  not be implemented via mkinitrd. Dracut is doing early microcode loading.
