[Sat] Consider any connection that reports NTN to be connected

For the sake of the device-based satellite icon interactor, this CL
changes the logic so that any mobile interactor that reports
`isNonTerrestrial` is considered to be "in service". This is because any
mobile connection that reports isNonTerrestrial will always show a
satellite icon for that connection (even if it's lost service), and we
don't want to show the Satellite SOS icon alongside it.
