UIFe: Notification for livepatch are not shown.

[Andrea Azzarone]

Hi doc/translators,

In order to properly show Livepatch notification in Bionic we need to
install some desktop files in /etc/xdg/autostart/ in order to woraround a
problem with the Systemd user session. The deskop files contain some
translatable strings but they're marked as "NoDisplay=True", so the impact
of non-translated strings should be minimum.

The bug report:

The merge request:

Thanks!
