"nixos-rebuild build-vm-with-booloader" with systemd-boot is broken again #107255
Description
Describe the bug
nixos-rebuild build-vm-with-booloader on a NixOS configuration with systemd-boot as bootloader (the default for NixOS installs on UEFI systems) fails with this error:
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
mount: /sys/firmware/efi/efivars: mount point does not exist.
I checked that the efivarfs.ko.xz file exists, so what's missing in the kernel since it reports "No such device"?
Steps to reproduce
$ 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

This happens with nixos-20.09 and nixos-unstable, but not nixos-20.03. (Just change the nixos-rebuild command above.)
Expected behavior
The build succeeds, like it did before (on nixos-20.03).
