[ci] Update Jenkinsfile build artifact gathering

Previously, hw_deployment_* directories were being found. The result
of this "find" was a list of directory paths which Jenkins was not
handling correctly. Removed this find and instead wrapped the copy in
a try/catch, if an error occurs catch it and error accordingly.
