lib/test/unit: refactoring puke

• lib/test/unit.rb (Test::Unit::Runner#puke): modify only result and
  drop useless reports, not override entirely.
• lib/test/unit/parallel.rb (Test::Unit::Worker#_run_suite): report
  unformatted results. formatting messages is not a workers task.
• lib/test/unit/parallel.rb (Test::Unit::Worker#puke): store raw
  results.
