perf hists: Add struct perf_hpp_list argument to helper functions

Adding struct perf_hpp_list argument to following helper functions:

  void perf_hpp__setup_output_field(struct perf_hpp_list *list);
  void perf_hpp__reset_output_field(struct perf_hpp_list *list);
  void perf_hpp__append_sort_keys(struct perf_hpp_list *list);

so they could be used on hists's hpp_list.
