Bug#836040: pango1.0: please use dbus-run-session to run tests

[Simon McVittie]

Source: pango1.0
Version: 1.40.1-1
Severity: normal
User: dbus at packages.debian.org
Usertags: dbus-launch dbus-launch-for-tests

As described in <https://lists.debian.org/debian-devel/2016/08/msg00554.html>
I'm trying to reduce how much dbus-launch is used in Debian.
This package currently uses dbus-x11 for tests, explicitly invoking
dbus-launch.

It should be possible to replace dbus-x11 as follows:

* replace the test dependency on dbus-x11 with dbus (>= 1.8)
* replace "dbus-launch xvfb-run -a gnome-desktop-testing-runner pango"
  with "dbus-run-session -- xvfb-run -a gnome-desktop-testing-runner pango"

Thanks,
