[nautilus/wip/toolbar-start-end: 76/77] toolbar: Wrap toolbar children in a GtkBox

[António Fernandes <antoniof src gnome org>]

commit d8f1397210b7c6ee9757185bb332e96724a0eaa2

    toolbar: Wrap toolbar children in a GtkBox
    
    GtkHeaderBar automatically provides spacing for its children.
    However, this spacing doesn't play well with hidden revealers.
    In order to not have double spacing, this commit creates GtkBoxes
    at both ends of the toolbar, and moves the margins to the children.
