please change polkit tty agent to exit silently if PK is not around

Description
currently, if systemctl forks off the tty PK agent and PK is not available you see two ugly error messages. It would be cool if the agent would simply exit silently if PK is not available, so that the systemd client tools are entirely clean if PK is not around.
The other option is of course to check whether PK is around first, and then fork off the agent, but given that each and all tools needing this would have to implement that on their own i think it would be nicer if the tty agent just quits silently on ServiceUnknown.
