[gnome-control-center] disable wacom on s390/s390x and non Linux platforms

[Bastien Nocera <hadess src gnome org>]

commit 0b782b5633249a1f8c15a24399a833ac2e41c6d5
Author: Antoine Jacoutot <ajacoutot gnome org>

    disable wacom on s390/s390x and non Linux platforms
    
    Follow gnome-settings-daemon behavior and disable the wacom panel on
    s390/s390x (because this architecture does not provide development files
    from the wacom xorg driver) and on non Linux platforms (where udev is
    missing).
