Turbostat: fix some WARNING/ERROR calls
Turbotat: tcc_activation_temp is a package concept, so store it in packages
Turbostat: Allow users to specify the TCCActivationTemp for unsupported CPUs
Turbostat: get rid of cpu migration altogether

There is no evident needs to migrate from cpu to cpu during the
exection. Furthermore, the affinity is not reset after the plugin run,
meaning that collectd would always run on the last processor.
