Change interrupted tests to report having a "timeout" test status

for test_info in self.test_infos:

  status = test_info.status

  if status == "error":

      # Don't distinguish between failures and errors.

      status = "fail"

  elif status == "timeout":

      # Until EVG-1536 is completed, we shouldn't distinguish between failures and

      # interrupted tests in the report.json file. In Evergreen, the behavior to sort

      # tests with the "timeout" test status after tests with the "pass" test status

      # effectively hides interrupted tests from the test results sidebar unless

      # sorting by the time taken.

      status = "fail"
