jenkins: use a full name of the --keep-img option

CRIU test suite run: error: ambiguous option: --keep could match --keep-img, --keep-going

It worked fine without the --keep-going option.

[xemul: Remove the --keep-going and --report options, the run
        of zdtm.py is not of much interest for TAP ]
