[gnome-software] Show app selection button based on gsettings

[Joaquim Manuel Pereira Rocha <jrocha src gnome org>]

commit 48d85af44711d8af07803f846979f92c396a2bea

    Show app selection button based on gsettings
    
    The selection button in the "installed" page is currently used only for
    folder management which is a feature that may not be useful for every
    vendor. For that reason, these changes introduce a new gsetting
    "show-folder-management" that is used to control the visibility of the
    app selection button.
