testBlinkPerfTracingMetricsForMeasureTime failing on Android Nexus 5 but not 5X (CQ)

Issue description

testBlinkPerfTracingMetricsForMeasureTime failing on Android Nexus 5 (linux_android_rel_ng) but not 5X (android_n5x_swarming_rel)

linux_android_rel_ng log:
https://chromium-swarm.appspot.com/task?id=35c420b37bd3cf10&refresh=10&show_raw=1


android_n5x_swarming_rel log:

This is super weird, as I don't expect there is much different between the two devices :-/

wangxianzhu@: could it be that the painting code in the test can only run 5x?
 
The biggest difference between the devices is OS. The nexus 5 runs K (KTU84P) and the 5X runs M (MMB29Q)
Maybe just because Nexus 5 is slow and needs a bigger timeout?

Simplify test file used by testBlinkPerfTracingMetricsForMeasureFrameTime & enable it on Android

This test was failing on Android Nexus 5 device due to the loading taking
too long. Simplifying its test case seems to fix the problem.
