nixos/networkd: fix typoed hairpin option name

You can see in https://www.freedesktop.org/software/systemd/man/latest/systemd.network.html that
this should be "HairPin" not "Hairpin". Using "Hairpin" results in

```
Oct 25 18:55:03 my-host systemd-networkd[843736]: /etc/systemd/network/10-bridge.network:11:
    Unknown key name 'Hairpin' in section 'Bridge', ignoring.
