This doesn't work for WebRTC since this script doesn't exist for our
instrumentation tests, just the native ones. These are the generated scripts we
have today:
run_audio_codec_speed_tests 
run_common_audio_unittests 
run_modules_tests 
run_peerconnection_unittests 
run_system_wrappers_unittests 
run_tools_unittests 
run_voice_engine_unittests 
run_webrtc_perf_tests 
run_audio_decoder_unittests 
run_common_video_unittests 
run_modules_unittests 
run_rtc_unittests 
run_test_support_unittests 
run_video_engine_tests 
run_webrtc_nonparallel_tests 

I also noticed those scripts don't reference our own test runner:
https://chromium.googlesource.com/external/webrtc/+/master/webrtc/build/andro...
so they won't run.

Let's work together on resolving these issues. For now, can we just exclude the
WebRTC bots from this change?
