[gtk+] Use gtk_text_layout_get_iter_at_line

[Paolo Borelli <pborelli src gnome org>]

commit 397cbbef32c72efacb68a6c62df73f1ddbe4373e
Author: Paolo Borelli <pborelli gnome org>

    Use gtk_text_layout_get_iter_at_line
    
    We already have a gtk_text_layout_get_iter_at_line wrapper that takes
    care of getting the btree from the layout, we may as well use it.
