[gnome-initial-setup/fix-blank-avatar] Change generated avatar for empty name

[Philip Chimento <pchimento src gnome org>]

    Change generated avatar for empty name
    
    The default generated avatar consisting of a white circle looks broken
    at first sight. We special-case an empty name to be a neutral "bust in
    silhouette" character on an orange background, to show that the circle
    contains an avatar and hopefully make it seem more clickable.
