[avahi] Avahi 0.6.27

[Trent Lloyd]

Debian appear to have patched this

 * Added debian/patches/02_avahi_client.patch:
    - Let the client check if the daemon is already running instead of just
      trying to start it, which doesn't work if there is no service file (the
      service file is just meant for systems using system.d) (Closes: #590760)
