SharedDummyBackend: Increase test timeout

Trying to address one possible aspect of #173, that the parent shell
tester that checks for the child to be terminated did not wait long
enough

Also add a ps output for the process in question if we fail so we might
might get a glance at whether the process is stuck or not
