[gnome-software/wip/hadess/quit-means-quit] Make --quit close the front-end and the backend

[Bastien Nocera <hadess src gnome org>]

commit 106326a5768b5be70f82fc241d87e70172a19acd
Author: Bastien Nocera <hadess hadess net>

    Make --quit close the front-end and the backend
    
    To match both the option's description (“Quit the running instance”),
    and the fact that it's a command-line option for developers and
    command-line aficionados.
    
    This doesn't change the behaviour of the “Quit” action in the
    gnome-shell app menu.
    
    Closes: #844
