[PATCH 2/2] lttctl: Set correct state events channels on armall

Currently ltt-armall directs every marker event to the cpu channel. This
patch starts distributing important state events to the related channels
under control/. This helps, e.g., to keep track of process names in
hybrid mode where the cpu channel is overwritten and only the control
channels are read continuously.
