Switch from ifupdown to systemd-networkd for network configuration

It seems that ifupdown does not handle hotplug events ('allow-hotplug'
configuration) inside container and does not allow to ignore
missing interface on boot ('auto' configuration), which is not
suitable for this container configuration.

For some reason, in case of failure ifupdown will successfully
configure networking but kills DHCP client, so the network works
only until first IP address renew.

Use systemd-networkd instead. Debian 10 documentation recommends it
as a 'modern' network configuration method, making ifupdown 'legacy'.
