grub-efi-native: Add support for EFI ISO images
The iso9660 file system support needs to be added to grub in order to be able to correctly find the grub.cfg. The grub commands to locate the grub.cfg also needs to be encoded into grub's default configuration. This change allows the resulting grub binary to work both in the hard drive / USB boot case or the optical media boot case.
