Convert isohybrid to regular iso

A plain i386 iso (not isohybrid) was needed for an old mac mini, but all the devuan images are isohybrid. It's possible to turn an isohybrid file into a plain CD iso. Here's a detailed account of how to do it:

Here's a brief description:
- mount the isohybrid
- copy the contents to an empty directory (myiso/ in the example below)
- repack the contents into a new iso file using xorriso:

xorriso -as mkisofs -r -J -joliet-long -rr -l -partition_offset 16 -V test-devuan-live -b isolinux/isolinux.bin -c isolinux/boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table -eltorito-alt-boot -o my-new.iso myiso/
