[gnome-settings-daemon/docking-stations] When the lid closes, suspend if all non-laptop RANDR outputs are off

[Federico Mena Quintero <federico src gnome org>]

commit 2700fd1708f8d6a61706ab3dbed12d51a8a9915d
Author: Federico Mena Quintero <federico gnome org>

    When the lid closes, suspend if all non-laptop RANDR outputs are off
    
    Now, we don't look at up_client_get_is_docked().  Instead, we rely on whether
    there are usable RANDR outputs - the laptop's is not a usable output if the
    lid is closed.  This may need refining in the future.
