Temporarily remove telemetry{,perf_}_unittests from Mac10.{10,11} Tests.

telemetry_unittests and telemetry_perf_unittests are consistently
failing on Mac10.10 Tests and Mac10.11 Tests. Due to a bug in recipes
code, the failures are not causing the builds to fail, so they are
consuming resources and not producing any useful signal.
