units: drop Before=sockets.target from networkd resolve hook

Otherwise, it introduces cyclic dependencies:
```
systemd[1]: sockets.target: Found ordering cycle:
    systemd-networkd-resolve-hook.socket/start after network-pre.target/start after
    iptables.service/start after basic.target/start after sockets.target/start -
    after systemd-networkd-resolve-hook.socket
systemd[1]: sockets.target: Job systemd-networkd-resolve-hook.socket/start deleted
    to break ordering cycle starting with sockets.target/start
```

Follow-up for 37adb410a2b62716b666dbf8359edf8a6546ff94.
Fixes #42353.
