Subject: scripts/oe-build-perf-report: show recipe version changes in html
 report

If buildstats are available (for a certain measurement), show recipe
version changes between the two builds that are being compared. The
information shown includes new and dropped recipes as well as changes in
recipe version, revision or epoch.
