[gtk+] Don't export _gtk_cell_renderer_calc_offset

[Matthias Clasen <matthiasc src gnome org>]

commit 88366ad5fe4a8a20a41cb73585ca7e1eb3ffca87

    Don't export _gtk_cell_renderer_calc_offset
    
    This is just a private convenience function, and exporting _-prefixed
    functions doesn't work with our libtool setup. Just do the 3 line
    calculation in gail.
