ci/lava: Stop printing after the result line

ci/lava: Stop printing after the result line

There are some leftovers in the jobs logs after the result log line.
Only print until the init-stage2.sh output, to raise the chance to check
for the test script results at the first glance in the Gitlab logs.

Extra changes:
- Add `hung` status for jobs considered hanging in the Gitlab
- print them after the retry loop
