…o `LinkLocalAddressing`

Both options were introduced in systemd v243[1]. Those options can be
used to ensure that LinkLocalAddressing is only configured for a given
interface if DHCPv4 fails. To quote `systemd.network(5)`:

```
If "fallback" or "ipv4-fallback" is specified, then an IPv4
link-local address is configured only when DHCPv4 fails. If "fallback", an IPv6 link-local
address is always configured, and if "ipv4-fallback", the address is not configured. Note
that, the fallback mechanism works only when DHCPv4 client is enabled, that is, it requires
"DHCP=yes" or "DHCP=ipv4".
```

[1] systemd/systemd@8bc17bb

I chose that version because [1] suggested that CEF versions before 75.x
worked, whereas newer versions don't compile due to API changes.

The version number corresponds to "git describe --tags".
