packaging-nix: add direnv support using the nix flake

Add an `.envrc` file and add the `.direnv` directory to `.gitignore`. `direnv` will check whether `nix` is available and `flakes` are enabled before trying to load the environment from `packaging/nix`. Using flakes from the `direnv` stdlib requires `direnv 2.30.0` or later. Signed-off-by: Philipp Jungkamp <[email protected]>
