runqueue: Ensure setscene tasks with overlapping stamps don't parallel execute
In multiconfig, mutliple tasks can execute which share the same stamp file. These must not execute in parallel, the idea is the first should execute, the subsequent ones should see a valid stamp and get skipped. The normal task execution code has stamps code to handle this, this adds similar code to the setscene execute() function to handle the issue there too. Signed-off-by: Richard Purdie <>
