I changed this in order for the Tether pattern to match in
NetworkStateHandler::GetNetworkListByType(). Is that fine?

I'm worried about other uses of NetworkTypePattern::NonVirtual that may not
handle the tether type correctly. I would rather request tether networks
separately / specially, at least for now.

Got it. Undid this, and changed NetworkListMd::Update to specifically grab
Tether networks.
