wireshark: additional dependencies

Wireshark without d-bus results in Wireshark demanding it and will
crash on capture. There’s a bug report at seclists here:
http://seclists.org/wireshark/2014/Apr/146 - That remains an issue with
the latest release as well. Without d-bus, wireshark is not happy.
wireshark: update 1.12.2 bottle.
