Skip Cronet tests that call GetTaggedBytes() on P+ devices.

In Android P, /proc/net/xt_qtaguid/stats is no longer guaranteed to be
present, and has been replaced with eBPF Traffic Monitoring in netd. See:

To read traffic statistics from netd, apps should use the API
NetworkStatsManager.queryDetailsForUidTag(). But this API does not provide
statistics for local traffic, only mobile and WiFi traffic, so it would not
work in tests that spin up a local server. So for now, GetTaggedBytes is
only supported on Android releases older than P.
