perf tools: Prevent condition that all sort keys are elided

If given sort keys are all elided there'll be no output except for the
overhead column - actually the TUI shows a noisy output.  In this case
it'd be better to show up the sort keys rather than elide.

Before:

  $ perf report -s comm -c perf
  (...)
  # Overhead
  # ........
  #
     100.00%

After:

  $ perf report -s comm -c perf
  (...)
  # Overhead  Command
  # ........  .......
  #
     100.00%     perf
