[RFC] util/liveiso: Add initial NixOS config for corebootiso

Add a NixOS configuration for a bootable live system containing a set of
tools which might be useful for working on firmware in general and
coreboot.

It can be built using build-console.sh, which requires Nix utilities to
be installed.

After building, the resulting iso image can be found in
`result/iso/nixos.iso` and its size is about 676MB.

An additional configuration for a variant with Gnome Shell as window
manager installed is WIP.
