[gnome-shell] switchMonitor: Only show 'mirror' and 'join' modes when not a laptop

[Marge Bot <marge-bot src gnome org>]

commit 37271ffe709fc957a6c24a28050c279e01e7013a

    switchMonitor: Only show 'mirror' and 'join' modes when not a laptop
    
    The 'external only' and 'builtin only' options makes no sense if there
    are only external monitors.
