lib.sh: Fix mcp key owner for OPNFV Jenkins jobs

In case of non-root deploys (i.e. running `ci/deploy.sh` without
sudo), the OPNFV Jenkins slave executes it under a user shell,
under a root shell, e.g.:
$ sudo sudo -u jenkins bash
$ echo $USER
jenkins
$ echo $SUDO_USER
root

Adjust lib.sh to only use SUDO_USER when it is not "root".
