nixos/docker: fix evaluation when NAT is enabled too

Browse source 
Both networking.nat.enable and virtualisation.docker.enable now want to
make sure that the IP forwarding sysctl is enabled, but the module
system dislikes that both modules contain this option.

Realistically this should be refactored a bit, so that the Docker module
automatically enables the NAT module instead, but this is a more obvious
fix.
