Android sheriff observers similar issues in issue 901278.

There is also issue 872264 from Aug 8, which has similar error log for testHideBrowserControlsAfterFlingBoosting 

Adding bokan@ who added both tests.

I can't find any obvious culprit, disabling the tests.

Moreover in https://ci.chromium.org/p/chromium/builders/luci.chromium.ci/Android%20CFI/3500 only org.chromium.chrome.browser.fullscreen.FullscreenManagerTest#testHideBrowserControlsAfterFlingBoosting fails, so they indeed look flaky.
