Whether a network is deemed roaming or not was already being tracked as part of the NetworkIdentitySet, so the underlying data store already tracks roaming and native data separately. However, this data was being aggregated together in NetworkStatsCollection#getSummary, since the NetworkIdentitySet is converted to an iface name for the purposes of matching, and the iface name will be identical whether or not the iface is considered roaming. Now it is separated. Also fixes a long-standing bug in NetworkIdentitySet where an identity read from a saved file would always be considered roaming == false, even if it wasn't at the time it was written.
