Subject: [PATCH] nixos/zerotierone: switch from manually generating the .link
 file to use the module

Previously, systemd.network.links was only respected with networkd
enabled, but it's really udev taking care of links, no matter if
networkd is enabled or not.

With our module fixed, there's no need to manually manage the text file
anymore.
