When running cyclictest in rteval, cyclictest automatically disables idle states. This means whenever the user sets the idle state of a cpu list using '--idle-set' it is overridden by cyclictest. To fix this, the variable 'usingCpupower' is appended to the parameter dictionary that's passed to the Cyclictest measurement object which executes cyclictest in rteval. If '--idle-set' is specified when running rteval, 'usingCpupower' is set to true and the '--default-system' option is appended to the cyclictest command, which will prevent cyclictest from disabling cstates.
