Ivan Trubach e5b072eca1 nixos/iso-image: add an option to disable BIOS boot
This change adds an option to disable legacy BIOS boot support for ISO
images. The implementation uses syslinux package that currently does not
support non-x86 platforms and thus cannot be cross-compiled, e.g. from
AArch64 system.
