signal-desktop: fix screensharing on wayland

Browse Source 
Without this change, starting a screenshare in signal-desktop on wayland
(sway) only produces a blank, black screen after selecting which screen
to share, with the following error in the logs:

ERROR:shared_screencast_stream.cc(412)] Unable to open PipeWire library
ERROR:base_capturer_pipewire.cc(81)] ScreenCastPortal failed: 1

Upstream has fixed screensharing in general according to
https://github.com/signalapp/Signal-Desktop/issues/5350#issuecomment-1664092786.
