Comment 18 for bug 1771740

Some more smaller remarks:
* We can drop the bundled "Implement-YAML-state-tracking-and-use-it-in-the-DBus.patch" from the Hirsute and Focal debdiffs (it has already been SRUed in the meantime).
* We need to fix the version strings (https://wiki.ubuntu.com/SecurityTeam/UpdatePreparation#Update_the_packaging), by basically just adding 0.1 to the current version for a normal SRU like this.

Impish => 0.103-0ubuntu7.1
Hirsute => 0.103-0ubuntu5~21.04.3
Focal => 0.103-0ubuntu5~20.04.3

I can apply those small fixes locally, so no need to update the debdiffs.
