Hopefully fix issue #25153459: Sandboxed_process1 thrashing

There is a race where if you unbind to a service before its
process has come up, we would leave the service record active
and keep it running.  Fix this by checking the service state
after its process up and proceed to bring it down if it is no
longer needed.

Also added a similar check when restarting a service, just in
case there are other ways we can get into this situation.

And while I am at it, I tweaked the broadcast queue dump output
a bit to hopefully make it a lot easier to figure out how long
it is taking to process broadcasts.
