[OSSTEST PATCH 34/60] sg-report-job-history: Use one child per report

[Ian Jackson]

Rather than one child per job, which then did one report per branch.

This will mean we can use the cache machinery, which is rather global
so wouldn't cope well with processing multiple job history reports
within a process.
