grub2.inst: Add support for creating iso9660 boot image

Browse source 
Don't include the "location" offset, and use just a path for the prefix
section to set the path of the grub2 modules on the iso. eg.

{
    "filename": "eltorito.img",
    "platform": "i386-pc",
    "core": {
        "type": "mkimage",
        "partlabel": "gpt",
        "filesystem": "iso9660"
    },
    "prefix": {
        "path": "/boot/grub2/"
    }
}
