Skip Autovacuum check for ci_builds related BBMs

What does this MR do and why?

Skips auto-vacuum health check performed to throttle BBM jobs for ci_builds based on the FF (skip_autovacuum_health_check_for_ci_builds).

Reasoning can be found here: #422834 (comment 1694864673).

Note: There are no sidekiq workers opted in to throttle with ci_builds table, so it should not be affected.
