Bug#835876: debian-policy: please suggest dbus-run-session to run tests

[Simon McVittie <smcv@debian.org>]

Source: debian-policy
Version: 3.9.8.0
Severity: minor
User: dbus@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.

The autopkgtest document in debian-policy currently mentions dbus-launch
as a possible wrapper around test commands. Please mention dbus-run-session
instead. Pseudo-patch:

  existing upstream test executable and just need to wrap it with some command
- like `dbus-launch` or `env`, you can use this field to specify the shell
+ like `dbus-run-session` or `env`, you can use this field to specify the shell
  command directly. It will be run under `bash -e`. This is mutually exclusive

Thanks,
