perf tools: Use hpp_dimension__add_output to register hpp columns

The perf_hpp__init currently does not respect sorting dimensions and the
setup_sorting function could endup queueing same format twice. That
screwed up the perf_hpp__list and got stuck in loop within
perf_hpp__setup_output_field function.

  $ perf report -F +overhead

Using hpp_dimension__add_output function to register the output column.
It will also mark the dimension as taken and omit above stuck.
