update-notifier-crash.service fails with apport-kde and no apport-gtk

[Daniel Tang]

update-notifier-crash is hardcoded to launch apport-gtk even though the update-notifier package only suggests the apport-gtk package. This results in the service failing and `systemctl --user status` showing "degraded".

$ lsb_release -rd
Description: Ubuntu Kinetic Kudu (development branch)
Release: 22.10

$ apt-cache policy update-notifier

$ dpkg --get-selections | grep ubuntu-desktop
ubuntu-desktop install
ubuntu-desktop-minimal install

This is a minimal Ubuntu install with KDE packages added on top.

$ dpkg --get-selections | grep apport
apport install
apport-kde install
python3-apport install

# Expected behavior

I don't want to see red in `systemd --user status` or any failed services.
Specifically, the update-notifier-crash service should not be enabled on KDE.

# Actual behavior

$ systemctl --user status
● daniel-desktop2
    State: degraded

# Analysis

My crash notifications are working fine on KDE even without this as confirmed by `(xclock &); sleep 1; killall -8 xclock`.

Either /usr/lib/update-notifier/update-notifier-crash needs to check for the existence of apport-gtk, or /usr/lib/systemd/user/update-notifier-crash.service needs to be masked on KDE.
