If DBUS_SESSION_BUS_ADDRESS is not set, trying to access the session bus
will autolaunch a new bus. Autolaunching doesn't work without X11.

We could check whether DBUS_SESSION_BUS_ADDRESS is set and launch the
bus manually from Pulseaudio, but then clients probably wouldn't find
the session bus, since the appropriate DBUS_SESSION_BUS_ADDRESS
environment variable would only be defined within the Pulseaudio
process.

It would be nice if also the non-X11 sessions would set up the session
bus already at login time, but I guess we can't rely on that. I'd expect
the user bus work to solve this problem eventually, but until that
becomes ubiquitous, I think putting module-dbus-protocol inside
a .nofail section would be the best workaround.
