[glibmm] Update some @newin commands

[Kjell Ahlstedt <kjellahl src gnome org>]

commit e041a10d625aa5f5f0ec1fecf293020d2501a4bd
Author: Kjell Ahlstedt <kjellahlstedt gmail com>
Date:   Thu Apr 26 13:13:33 2018 +0200

    Update some @newin commands
    
    API which is new in the future ABI-breaking release is newin{2,58},
    but this might change again in the future. glibmm-2.58 is still just a
    preliminary name of this ABI. Bug 789330
