[2.2] Improve systemd services dependencies

[rdmark]

atalkd will fail to start unless a network connection is established. All other DDP services depend on atalkd to have started first, so make them do the same.

This is critical for when netatalk is running on a device that only has a wlan interface, such as an RPi Zero W.

Addresses #232

Also pulls in the improvement from downstream https://sources.debian.org/src/netatalk/3.1.14~ds-1/debian/patches/104_modernize_systemd.patch/

@marcuskuenzel1971 I suggest you edit the *.service files that are installed on your system already. If you run the command systemctl status atalkd you can find where atalkd.service is located, for instance. In my case, they're under /lib/systemd/system/

$ systemctl status atalkd
● atalkd.service - Netatalk AppleTalk daemon
     Loaded: loaded (/lib/systemd/system/atalkd.service; enabled; vendor preset: enabled)
     Active: active (running) since Sun 2023-02-26 19:26:42 PST; 2 days ago
    Process: 5620 ExecStart=/usr/local/sbin/atalkd (code=exited, status=0/SUCCESS)
      Tasks: 1 (limit: 1596)
        CPU: 2.868s
     CGroup: /system.slice/atalkd.service
             └─5621 /usr/local/sbin/atalkd

Edit the file (requires sudo) then save and run the command sudo systemctl daemon-reload
