grub2: prepare and install El Torito image
In order to support ISO9660 bootable images that rely on Grub 2, this
commit modifies thr Grub 2 makefile to generate and install an El
Torito image. Such an image is simply produced by concatenating the
cdboot.img provided by Grub 2, and the Grub 2 image generated by
Buildroot using grub-mkimage.
Since this action is so simple and cost-free, we don't bother adding a
Grub 2 sub-option for that, and simply generate the El Torito image
unconditionally.
