networkd: add minimal IP forwarding and masquerading support to .network files
This adds two new settings to networkd's .network files: IPForwarding=yes and IPMasquerade=yes. The former controls the "forwarding" sysctl setting of the interface, thus controlling whether IP forwarding shall be enabled on the specific interface. The latter controls whether a firewall rule shall be installed that exposes traffic coming from the interface as coming from the local host to all other interfaces. This also enables both options by default for container network interfaces, thus making "systemd-nspawn --network-veth" have network connectivity out of the box.
