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.
