[gnome-control-center] sharing: Use a HdyColumn and a GtkScrolledWindow

[Georges Basile Stavracas Neto <gbsneto src gnome org>]

commit 5be6fc4d1fd3245dedcbe408df23ee1ac42b7585
Author: Adrien Plazas <kekun plazas laposte net>
Date:   Wed Feb 20 15:25:18 2019 +0100

    sharing: Use a HdyColumn and a GtkScrolledWindow
    
    Put the widget's content into a HdyColumn, itself into a
    GtkScrolledWindow. This allows the panel to reach narrower sizes.
    
    This deliberately doesn't adapt the indentation of the contained widget
    to help this commit to be more readable and easier to review, it will be
    adapted in the next commit.
