Subject: perf tools: Suggest inbuilt commands for unknown command

The existing unknown command code looks for perf scripts like
perf-archive.sh and perf-iostat.sh, however, inbuilt commands aren't
suggested. Add the inbuilt commands so they may be suggested too.

Before:

  $ perf reccord
  perf: 'reccord' is not a perf-command. See 'perf --help'.
  $

After:

  $ perf reccord
  perf: 'reccord' is not a perf-command. See 'perf --help'.

  Did you mean this?
          record
  $
