Fix meaning of "provide net"

I was informed that "provide net" should mean that there is network
communication outside the local computer. In this case, the loopback
interface can't "provide net", but there needs to be a way for other
processes to know that the loopback interface is active.

To this end, this commit makes the loopback "provide lo" and all other
interfaces "provide net".
