Subject: [PATCH] [Chore] Fix overlay

Problem: In my recent PR(#264), I accidentally picked overlay output
changes from the philtaken/nixos-vm-tests branch, which broke existing
overlay imports after updating the deploy-rs input.

Solution: Add backwards compatibility so that users don't have to make
changes to their nix flakes.
