temp/gnome-control-center: enable printer panel

The bug that made the cups client in the panel crash is now fixed and the panel is finally usable!!!! Additionally, bump to 41.2 to get more translations.

One less patch, one more feature 🎉

However, for the printer panel to be totally usable, the cupsd has to be started (and it is not by default as alpine's policy). Would it be appropriate to add the dependency to postmarketos-ui-phosh and enable the daemon?

Also, the fix is likely to be backported to 3.15. It is probably not coming on time for 21.12, but maybe for the first service pack?
