Check in prebuilt test runner

In instant mode apps cannot access data/local/tmp where
the instrumentation runner stores meta-data. Now we use
a shell command to read the files and this change is a
check in of a prebuilt with the fix.

Test: cts-tradeted run cts -m CtsAccessibilityServiceTestCases
      cts-tradefed rin cts-instant -m CtsAccessibilityServiceTestCases
      all Google3 presumit tests pass
