Use latest Network device naming scheme (#2763)
This essentially reverts #2380, making sure that Home Assistant OS uses
systemd's latest network naming scheme.

We stick to a certain naming scheme to make sure NetworkManager still
applies the network configuration (which is matched by network interface
name by default).

With Supervisor [PR #4476](https://github.com/home-assistant/supervisor/pull/4476)
NetworkManager uses udev path by default. With this we can safely enable
the new interface naming and NetworkManager will still apply the
configuration based on udev path correctly.
