Revert of Enable viewing render tests results on buildbot on Android FYI bot....

Revert of Enable viewing render tests results on buildbot on Android FYI bot. (patchset #1 id:1 of https://codereview.chromium.org/2625673003/ )

Reason for revert:
Reverting since the FYI bot seems to be having trouble running chrome_public_test_apk (seems like device or adb issue). Enabled this on another bot (M tester on chromium.android).

Original issue's description:
> Enable viewing render tests results on buildbot on Android FYI bot.
>
> Adding example test with render tests to FYI bot. If everything
> works as intended, will enable this on all bots. Will also switch
> implementation from needing to be configured by manually setting
> render_results_dir to detecting the render_results_dir automatically.
