[gnome-bluetooth] settings: Align the explanatory text with the listbox

[Bastien Nocera <hadess src gnome org>]

commit 78af0b0a46c1b53208e8fbbccdc3b3416237cba4
Author: Bastien Nocera <hadess hadess net>

    settings: Align the explanatory text with the listbox
    
    The text was a couple of pixels (4 to be exact) more inside the page
    than the listbox. Make the margin apply to the box containing both the
    listbox and the explanatory text so that there's no minute discrepancy
    in alignment.
