kiwix-tools: init at 3.4.0

this provides the `kiwix-serve` tool asked for in
<https://github.com/NixOS/nixpkgs/issues/35009>,
but does not implement the systemd service requested.

package contents:
- bin/kiwix-manage
- bin/kiwix-search
- bin/kiwix-serve

tested by invoking `kiwix-serve` and connecting to it in a web browser:

```sh
nix build '.#kiwix-tools'
wget 'https://dumps.wikimedia.org/other/kiwix/zim/wikipedia/wikipedia_en_simple_all_mini_2022-11.zim'
./result/bin/kiwix-serve -p 1080 ./wikipedia_en_simple_all_mini_2022-11.zim
curl http://localhost:1080
```
