Subject: [PATCH] Fix snap package: printing and print-preview (backport to
 1.4.x)

- Printing needs cups -> trigger host-side installation of the cups snap socket (or however it is called)
- Print preview needs evince (which needs some further stuff) --> include it in the snap until a better solution is found

Fixes #1734 for 1.4.x
