[v3] trace-cmd: List ftrace instances at the end of trace-cmd stat

Commit Message

By default, "trace-cmd stat" command prints status of the main ftrace
instance. At top of the output there is a listing of all configured
instances abd the user could be confused which status is displayed.
Moved this list at the end of the command output.

v3: Removed the "main" when top instance is displayed and move instance
    listing at the end of command's output.
