perf tools: Do not elide parent symbol column

I found the parent symbol column data interesting even
if there's another sorting enabled. Switching it on.

Previous behaviour:
  $ perf report -i perf.data.delete -p perf_session__delete -x

  +   3.60%  perf  perf               [.] __rb_change_child
  +   1.89%  perf  perf               [.] rb_erase
  +   1.89%  perf  perf               [.] rb_erase
  +   1.83%  perf  perf               [.] free@plt

Current behaviour:
  $ perf report -i perf.data.delete -p perf_session__delete -x

  +   3.60%  perf  perf               [.] __rb_change_child        perf_session__delete
  +   1.89%  perf  perf               [.] rb_erase                 perf_session__delete_dead_threads
  +   1.89%  perf  perf               [.] rb_erase                 perf_session__delete_threads
  +   1.83%  perf  perf               [.] free@plt                 perf_session__delete
