[gnome-shell] Define externally accessible contants with 'var' instead of 'const'

commit 033277b68f2910e54ce62f45fa92af2f5092a7ba
Author: Florian Müllner <fmuellner gnome org>
Date:   Tue Jul 18 19:47:27 2017 +0200

    Define externally accessible contants with 'var' instead of 'const'
    
    Just as we did with classes, define other constants that are (or
    may be) used from other modules with 'var' to cut down on warnings.
