[gparted] Go back to symbolic label widget alignment constants

[Curtis Gedak <gedakc src gnome org>]

commit 45fd146fd0f7616518caaf77918c1735ad5af5ad

    Go back to symbolic label widget alignment constants
    
    Now that GParted requires Gtk3 there is no need to use floating point
    numbers for compatibility with Gtk <= 2.22.  Replace with symbolic
    alignment constants.
    
    Relevant commit history:
    
    *   6efa6234012b5fa112af4db08e0b89238d53981a
        Add optional yalign argument to Utils::mk_label() method
    
    *   be2689ad25c104e3cb97e7d5d1f7627dbb137b19
        Stop using deprecated widget alignment enumerators (#652044)
