Add support for building an hybrid ISO9660 image compatible with legacy and UEFI BIOS. Note that this is not about an (iso)hybrid image, which can boot from both a CDROM or a USB stick, but really about an image being bootable from the legay BIOS or EFI; the two are orthognal. The option -eltorito-alt-boot need to be used in the xorriso command to generate the hybrid image. That option is a separator, meaning the previous boot entry is done, and the following boot options define a new boot entry. The -no-emul-boot defines the type of the current boot image; that's why it has to now be repeated in each of the BIOS and EFI options. Finally, for symetry and consistency between the BIOS and EFI options, we move the BIOS image option first. Note: the BIOS boot image options have to be provided before the EFI ones, or the system won't boot; the underlying reason is not known...
