Vincent Ambo 33f30573f9 fix(tazjin/nixos): fix wayland screen sharing
Apparently something called a "desktop portal" needs to provide a magic
"service" and blabla; the TL;DR is that adding all this Gnome stuff makes screen
sharing work.

Tested using the Mozilla WebRTC test page:
https://mozilla.github.io/webrtc-landing/gum_test.html

Seems like our Chromium/Firefox are new enough not to require magic settings for
Wayland.
