[glibmm] MenuItem: Reimplement the constructors.

[Murray Cumming <murrayc src gnome org>]

commit 23823fdf3a54ed3851b8564fa8df993ce6e5e33f
Author: Murray Cumming <murrayc murrayc com>
Date:   Wed Jul 31 13:29:41 2013 +0200

    MenuItem: Reimplement the constructors.
    
    * gio/src/menuitem.[hg|ccg]: Because GMenuItem (and GMenu) do not
      have any properties and have actual code in their *_new() C
      convenience functions.
      Bug #705199 (Pete Woods)
