perf tools: Add callback function to hist_entry_iter
The new ->add_entry_cb() will be called after an entry was added to the histogram. It's used for code sharing between perf report and perf top. Note that ops->add_*_entry() should set iter->he properly in order to call the ->add_entry_cb. Also pass @arg to the callback function. It'll be used by perf top later.
