post_process: clearly delineate the beginning os script output.

This is a companion change to
https://review.spdk.io/gerrit/c/build_pool/jenkins_build_pool/+/1810
and the two should be merged together to make sure the entire output
of the post process script is included in one file when output from
the CI.
