make-disk-image: fix broken EFI image builds

Browse source 
Work around missing /dev files inside runInLinuxVM by creating a
symlink before calling nixos-enter.

This fixes https://github.com/NixOS/nixpkgs/issues/93381.
I ran into this issue when trying to create a VMware image that boots from EFI.

Thanks @colemickens for reporting this and @danielfullmer for fixing the same thing in in qemu-vm.nix (37676e77cb) and explaining what the issue was.
