[test-expectations.html] Remove rebaseline output format

The wrapped text format can be used for rebaseline: just copy the wrapped
text output and paste it into a command line like starting with
  run-webkit-tests --reset-results

Discussed offline with Xiaocheng who developed the feature and we agreed
to remove the feature to avoid maintaining another rebaseline tool.
