Bugfix: Dovetail CI failed on fuel because of BRANCH: unbound variable

JIRA: DOVETAIL-451

1. Dovetail CI jobs failed on fuel becase lack of BRANCH.
   fetch_os_creds.sh: line 75: BRANCH: unbound variable
2. That's mainly because of Dovetail uses sudo to run fetch_os_creds.sh.
3. BRANCH is jenkins' env param and root's env lacks of this param.
