{gradle.fetchDeps,shattered-pixel-dungeon}: fix eval on Nix 2.3.18

[philiptaron]

Motivation

I discovered this problem developing tests for nixpkgs-check-by-name in NixOS/nixpkgs-vet#79. Nix 2.3.18 is nixVersions.minimum.

The changes were introduced in #272380. CC @chayleaf.

Description of changes

• Use ./. + "relative path" instead of constructing a path with newer Nix syntax.
• Use lib.compareLists instead of comparing lists directly.

Things done

• Built on platform(s)
  • x86_64-linux
  • aarch64-linux
  • x86_64-darwin
  • aarch64-darwin
• Tested, as applicable:
  • Nix 2.3.18 (nixVersions.minimum)
  • Nix 2.23.2 (nixVersions.latest)
  • Nix 2.18.5 (nixVersions.stable)
• Fits CONTRIBUTING.md.

OK, this should be better.

which is more correct, so LGTM (nit: the diff could be made smaller by inlining the compare function)
