Fix testIkeOverUdpEncapSocket flakiness caused by cached ifaceStats
Since the target SDK of this test should always equal or be
larger than V, TrafficStats caching is always enabled.
Clearing the cache is needed to avoid rate-limiting on
devices with a mainlined (T+) NetworkStatsService.
Test: atest CtsNetTestCases:android.net.cts.IpSecManagerTest#testIkeOverUdpEncapSocket \
--rerun-until-failure 100 (on T device with latest tethering module)
