mdraid/mdraid_start.sh: tell mainloop if we make progress.

mdraid_start is a number of scripts which run after a timeout.
If it makes progress, it should tell the main loop so that it
knows that it is worth waiting a bit longer.

So in that case, create the initqueue/work file which the main loop
checks for.
