Adel Gadllah f02b007337 shell-screenshot: Only allow one screenshot request at a time per sender
We currently allow infinite number of screenshot requests to be active at
the same time, which can "dos" the system and cause OOM.

So fail subsequent requests for the same sender when a screenshot operation
is already running.
