Subject: [PATCH] fix: nix flake smithay lock issues

* flake: use allowBuiltInFetchGit to prevent narHash reproducibility issues

using the builtin fetcher allows fetching git dependencies with only the ref and without storing the narHash for the fixed-output-derivation

* gitignore: add nix result symlinks
