[Bug 1807900] [NEW] update-manager suggests to use Livepatch, which is not available

[Christian Biscombe]

Public bug reported:

Ubuntu MATE 18.04.1
update-manager 1:18.04.11.7

Steps to reproduce:
1. After installing updates via update-manager, a dialog box appears stating 'Tip: You can use Livepatch to keep your computer more secure between restarts.' 
2. Click 'Settings and Livepatch...'.
3. software-properties-gtk launches, showing the 'Updates' tab. 
4. There is no option to enable Livepatch, either in the Updates tab or elsewhere.

Probably related to Bug #1770686. The dialog box should not suggest to
use Livepatch if gnome-control-center is not installed.
