Bob van der Linden 8d092270d2 nixos: iso-image: use syslinux bootloader for USB booting support
This changes the bootloader for iso generation from Grub to
syslinux. In addition this adds USB booting support, so that
"dd" can be used to burn the generated ISO to USB thumbdrives
instead of needing applications like UnetBootin.
