CTS runner fixes

1. For InstrumentationTest, don't set method, class, package names;
   this is because the list of test methods to run is already
   computed by test filtering and passed to runner via file based
2. For test failure logcat, change sleep from 10ms to 2s before
   capturing logcat after a failed test method.
