Removing Python modules causes the removal of Xorg

[Sergiu Bivol]

I tried to remove python3-keyring and was surprised to see that this would cause the removal of xorg and sddm.
The dependency chain is something like: python3-keyring <- python3-launchpadlib <- python3-apport <- xserver-xorg <- sddm.

It is completely unexpected and potentially embarrassing to end up with no graphical desktop after removing a random Python library.

python3-apport should not be a hard dependency of xserver-xorg.
