kernelshark: Have stop dialog close when command is finished

When the trace-cmd record command finishes, close the stop dialog.
Luckily we know when it finishes because the command will close
the pipe which will cause the monitor_pipes thread to detect
it. Then it will close the dialog box by emitting the delete-event
signal to it.
