android: attempt to diagnose flaky test list issues on android-asan.

This CL:
 - should ensure that failures to list tests hit the logcat logic
   in LocalDeviceGtestRun._GetTests rather than skipping it due to
   an exception raised by device.StatFile on a nonexistent file
 - avoids the adb 1.0.41 root timeout (again) on calls to
   asan_device_setup.sh --revert
