eclair: Add custom selection function to filter out B.REPORT for diff reports

When producing diff reports, we're interested in entries for B.REPORT
service, which is otherwise useful for non-delta reports. So, we don't
want to disable it altogether (on analysis phase), but want to filter
out specifically when producing delta reports. This solution is based
on the information from Bugseng in ticket
