Don't restart swaybg if the command hasn't changed

Browse source 
When outputs have changed but none of that has resulted in a change in
how swaybg should be run don't restart it. This avoids flickering the
background to grey as a result of bug #3693, and is generally good to
not churn through process termination and startup for a no-op.
