Review request for mesos and Till Toenshoff.


Fixed mistake in gtest filter.

Bugs: MESOS-3082

Repository: mesos


Virtual machines may not always support 'CPU performance counters'. Tests
trying to collect to 'cycle' value of 'perf' will fail under these
circumstances. This will be avoided by disabling these tests if 'perf' hardware
events are not available.


  src/tests/environment.cpp 20218a086baefcefb310eb45ed9024e5425ce787 


Testing (updated)

`sudo ./bin/ --gtest_filter="*ROOT_CGROUPS_Perf:*ROOT_CGROUPS_Sample:*ROOT_CGROUPS_UserCgroup:*CGROUPS_ROOT_PerfRollForward:*ROOT_Sample"`
in a VM without 'CPU performance counters'. This doesn't run any tests, as expected.
