Move TrafficStats iface counters to xt_qtaguid.

Use xt_qtaguid iface_stat_all counters, which are monotonic during
a single boot.

Track all ifaces associated with mobile networks since boot, and
move TrafficStats to using these ifaces.  This will include usage of
networks omitted from config_data_usage_network_types, specifically
on devices that recycle network interfaces across APNs.

Split wildcard template matching, and move NetworkStatsService to
use mobile wildcard when logging stats.
