[PATCH] unit: don't specify tcp hostname in dbus config

Testing dbus with no network interfaces available on the host fails
with:
  dbus-daemon[291]: Failed to start message bus: Failed to lookup host/port: "*:14046": Name or service not known (-2)

Seems like "*" isn't a valid hostname in such cases:
  https://bugs.freedesktop.org/show_bug.cgi?id=28979

According to the linked issue, the fix is to simply omit the host= and
bind= parameters in the config.
