[glib] Add non-symbolic fallback icons in g_content_type_get_symbolic_icon().

[Matthias Clasen <matthiasc src gnome org>]

commit e6af432b39ac9e0123387e5a993737073dce9153

    Add non-symbolic fallback icons in g_content_type_get_symbolic_icon().
    
    This makes the behavior consistent with e.g. g_volume_get_symbolic_icon().
