prl-tools: add wayland dependency

This is required for prlcc to function correctly in wayland sessions.

Previously, when using wayland, prlcc did not detect the session.
Features such as 'Use all displays in Full Screen' and adjusting the
resolution based on host window size were thus not available in Wayland
sessions.
