Add checks for detailed uid stats

Browse Source 
Get the detailed network stats for the test uid and check if the detail
stats is consistent with the per uid stats. This test is necessary since
the new devices may get detailed network stats and per uid total stats
from different eBPF maps.

Test: atest TrafficStatsTest
