utils/job-prereq.py: Use yaml safe_loadhalibut_7.99.3halibut_7.99.2halibut/7.99.3halibut/7.99.27.99.37.99.2

On my gentoo, using yaml.load now give:
Traceback (most recent call last):
  File "./utils/job-prereq.py", line 81, in <module>
    main()
  File "./utils/job-prereq.py", line 66, in main
    job_yaml = yaml.load(job)
  File "/usr/lib64/python2.7/site-packages/yaml/__init__.py", line 109, in load
    raise RuntimeError("Unsafe load() call disabled by Gentoo. See bug #659348")
RuntimeError: Unsafe load() call disabled by Gentoo. See bug #659348

Note that on recent ubuntu, a warning appears also. (like on AGL jenkins)
/w/workspace/ci-platform-meta-agl-demo-verify-CIBT-qemuarm64/repoclone/releng-scripts/utils/job-prereq.py:66: YAMLLoadWarning: calling yaml.load() without Loader=... is deprecated, as the default Loader is unsafe. Please read https://msg.pyyaml.org/load for full details.
  job_yaml = yaml.load(job)

This is due to a security risk of using yaml.load()

Since releng-script does not rely on any behavour provided by load(), let's convert the call to safe_load().
This will also clean/reduce the output of jenkins logs
