[gtk+] menuitem: share code between HFW and non-HFW height requests

[Cosimo Cecchi <cosimoc src gnome org>]

    menuitem: share code between HFW and non-HFW height requests
    
    The code is very similar; having two slightly different code paths is
    bad and can lead to bugs. Refactor the code to use the same height
    request function.
