Subject: [PATCH] pavucontrol: dropdown patch for wayland support

Pavucontrol employed a button with a popup instead of a dropdown menu
for it's dropdown menus. These were rendered offset to the window and
maybe even offscreen from the window. Add the upstream patch which fixes
this issue.

Fixes https://github.com/NixOS/nixpkgs/issues/87446
