perf hist: Remove output field from sort-list properly

When it removes an output format for cancelled children or latency, it
should delete itself from the sort list as well.  Otherwise assertion
in fmt_free() will fire.

  $ perf report -H --stdio
  perf: ui/hist.c:603: fmt_free: Assertion `!(!list_empty(&fmt->sort_list))' failed.
  Aborted (core dumped)

Also convert to perf_hpp__column_unregister() for the same open codes.

Committer notes:
