Bjørn Forsman 72d906a0ea nixos: fix "nixos-rebuild build-vm-with-bootloader" for EFI systems
(The first version of this change, in commit 39fad297fd, broke
`nix-build -A nixosTests.installer.simpleUefiSystemdBoot`. This is the
2nd version, which hopefully does not break anything.)

`nixos-rebuild build-vm-with-bootloader` currently fails with the
default NixOS EFI configuration:

  $ cat >configuration.nix <<EOF
  {
    fileSystems."/".device = "/dev/sda1";
    boot.loader.systemd-boot.enable = true;
    boot.loader.efi.canTouchEfiVariables = true;
  }
  EOF

  $ nixos-rebuild build-vm-with-bootloader -I nixos-config=$PWD/configuration.nix -I nixpkgs=https://github.com/NixOS/nixpkgs/archive/nixos-20.09.tar.gz
  [...]
  insmod: ERROR: could not insert module /nix/store/1ibmgfr13r8b6xyn4f0wj115819f359c-linux-5.4.83/lib/modules/5.4.83/kernel/fs/efivarfs/efivarfs.ko.xz: No such device

  builder for '/nix/store/dx2ycclyknvibrskwmii42sgyalagjxa-nixos-boot-disk.drv' failed with exit code 32
  [...]

Fix it by setting virtualisation.useEFIBoot = true when needed.

Before:
* release-20.03: successful build, unsuccessful run
* release-20.09 (and master): unsuccessful build

After:
* Successful build and run.

Fixes #107255
