Nix: fix the overlay and re-export properly (#26)

* flake: made systems overrideable

* flake: do not use legacyPackages

* flake: add overlay named hyprlang

* flake: overlays: do not recurse with rec

* flake: overlays: only use drvs from final fixpoint

* flake: packages: correctly eval own overlay
