fs/iso9660: add hybrid image support

This commit adds a new option, which allows, when isolinux is used as
the bootloader, to generate an "hybrid" ISO image. Such images can
either be booted from CD-ROM or from USB keys. It simply uses the
isohybrid tool provided by syslinux.

Enable this option to build an hybrid image, i.e an image
which can either be booted from a CD-ROM or from a device
which BIOS considers a hard disk or ZIP disk, e.g. a USB key
or similar.
