[PATCH OSSTEST] sg-report-job-history: alternate color of osstest column only when it changes

[Ian Campbell <ian.campbell@citrix.com>]

Currently the bgcolor of the osstest column alternates on each line,
rather than only when it changes as the other revision columns do.

A given flight might touch multiple osstest revisions (although in
practice they rarely do) but it seems reasonable to simply consider
any change as a change.
