kcidb: link tests to the right build job

For kcidb test objects we need a build_id to link to. The publish job stage has the most complete set of data, but it can fail. However, if publish stage fails, the 'test' job will not run anyway.

Thus, we should be able to link tests to publish job by overriding job_id in rc file under [build].

The most important thing is for the objects in "builds" and "tests" refer to a build that exists in the kcidb_all.json file; our dumpfile has to be internally consistent.
