If `qemu-vm.nix` is imported, the option `virtualisation.qemu.consoles` should be set to make sure that the machine's output isn't rendered on the graphical window of QEMU. This is needed when interactively running a NixOS test or in conjunction with `nixos-build-vms(8)`. The patch 257855753073987160c293fdedc9d95a33cbc0e8 tries to only do this if the option actually exists, however this condition used to be always false since `options` wasn't imported in the module and pointed to `lib.options` due to the `with lib;`-clause.
