Make networking a bit more configurable via NIC_TYPE.
This can be:
None
No networking at all.
br
bridge mode; NIC_NET_DEPS if set is the networking needed.
nat
Qemu user stack; NIC model is honored, but qemu itself spins up
a dhcp server and nats connections out on it's own. For most users
this is likely what they'll be using- thus this is now the default.
