Revert of Revert of Disable telemetry tests for Mac 10.9. (patchset #1 id:1 of https://codereview.chromium.org/744283002/)

Reason for revert:
This re-enabling of tests has left a trail of redness on Mac 10.9 (more than one failure). If you expect tests to fail as a result of re-enabling again, then please watch the tree and disable the ones failing (assuming that is the appropriate course of action in the first place, which I'm not sure of).

> Revert of Disable telemetry tests for Mac 10.9. (patchset #2 id:20001 of https://codereview.chromium.org/706703003/)
>
> Reason for revert:
> Second attempt to re-enable tests. I think there may still be one test failure, but we can disable that one test. If there's more than one, revert this.
