    wayland: Create XAuthority file once
    
    Where the prepare_auth_file() call is, it does create a new one on every
    respawn of Xwayland. This is not benefitial, as the XAUTHORITY envvar is
    already fixed in the session.
    
    Only create the XAuthority file once, and reuse it on future Xwayland
    respawns.
