Comment 1 for bug 1752024

Thanks Tim for reviewing those, some comments

* 22_support_autostart_delay.patch,

It's still useful and easy to maintain, let's keep it at least until the LTS. We don't have systemd user session yet, when we do (likely next cycle) then we can drop the patch and move from autostart to user jobs.

* 95_dbus_request_shutdown.patch,

unsure where it's used but it's easy to keep so let's avoid surprises by dropping it just before the LTS and do that next cycle?

* export_env_to_upstart.patch

seems fine to drop
