Currently, BatteryStatsService register netd callback and track radio
power state only for the default network.
So, battery stats are not accurate if cellular and Wi-Fi networks are
active at the same time.
aosp/2561090 updates BatteryStatsService not to register netd callback
on V+ devices.
This CL updates LegacyNetworkActivityTracker to call BatteryStats API
and update radio power state for networks including non default networks
on V+ devices.
