Use a separate map to store per app stats
To avoid iterating through the eBPF map to get the total stats of a
specific uid. A new bpf map called appUidStatsMap is added to the
trafficController so that TrafficStats API can directly read that map
for per uid total stats regardless of tag, counterSet and iface
information. This could make this call more efficient and solve the
possible racing problem.
