Revert "Update co19 to revision d4767b4caea3c5828ad8e053cd051d44a59061af"

This reverts commit a829cfff4b99d0cea250b8121eae1bf5430bc3db.
The co19 update often introduces many test failures, even after testing
locally and updating status files.  So we may revert the update, after
seeing which tests are failing on the buildbot, to do more updates on
the status files before landing again.
