[gnome-shell] src: Stop using g_get_current_time()

[Florian Müllner <fmuellner src gnome org>]

commit 9b7f228f8ef224c36fd8809942ec78ce071fdbd7
Author: Florian Müllner <fmuellner gnome org>
Date:   Wed Jul 31 20:29:46 2019 +0200

    src: Stop using g_get_current_time()
    
    It isn't 2k38 safe and has therefore been deprecated. Replace it
    with GDateTime or g_get_real_time() as appropriate.
