Handle local Zeroconf service name collisions.

Service name collisions from other servers have always been handled,
but not *local* name collisions from services on the same host.

* mandos (AvahiService/rename): Handle local Zeroconf service name
                                collision.
  (AvahiServiceToSyslog.rename): Pass on any extra arguments.
