Ian Rogers fc4577b52a perf test: Test pipe mode with data conversion --to-json
Add pipe mode test for json data conversion. Tidy up exit and cleanup
code.

Committer testing:

  $ perf test 'perf data convert --to-json'
  124: 'perf data convert --to-json' command test                      : Ok
  $ perf test -vv 'perf data convert --to-json'
  124: 'perf data convert --to-json' command test:
  --- start ---
