csm-manager.c: Unset WAYLAND_DISPLAY during shutdown in a wayland session. This and others need to be cleared after a wayland session so systemd doesn't pass them to the next session. This is performed by others using systemd unit parameters, but we don't currently use systemd for this. https://gitlab.gnome.org/GNOME/gnome-shell/-/blob/main/data/[email protected]?ref_type=heads#L26
