[CI] Exclude timed-out or stuck jobs from collection for the complexity/coverage webpage

Exclude timed-out or stuck jobs from collection for the complexity/coverage webpage - currently, the last occurence of a job is collected regardless of failure/success state (because there is the check for changes in the complexity numbers which fails the job if the numbers change). If a job timed out, it is stil collected, but no artifacts are found. This MR fixes this by excluding timed out jobs from being collected.
