network: Add virtio-net dependencies

Browse Source 
The newly added virtio-net implementation needs to interact with TAP
interfaces and MAC addresses, which is the reason why it is easier
to rely on existing packages net_util and net_gen.

One more thing, both net_util and net_gen could be trimmed down,
based on using only the things we need from cloud-hypervisor.

Both net_util, net_gen and sys_util are based on Firecracker
