The default behavior with an m3.medium instance is to relocate /nix and /tmp to /disk0 because an assumption is made that any ephemeral disk is larger than the root volume. Rather than make that assumption, add a check to see if the disk is larger, and only then relocate /nix and /tmp. This addresses https://github.com/NixOS/nixpkgs/issues/12613
