Viewing log output while tests are still running can be useful for debugging, but log output was previously always captured. This change ensures that log capture is off by default, but can still be enabled by setting OS_LOG_CAPTURE=1 in the shell environment. testr invocation is unchanged and will continue to capture logs by default.
