ci-workarounds/get_extra_logging.yaml : avoid grep failure

If this grep doesn't match, the task returns a failure and it causes
the job to abort with POST_FAILURE.  I think more info is generally
helpful and you can always grep "netstat" on the file manually; thus
remove the grep to avoid suprious failure.
