Reliable_report: ignore unconventional jobs

What does this MR do and why?

As per !130276 (merged) filters out results from the follow jobs from the reliability report:

• airgapped
• instance-image-slow-network
• nplus1-instance-image

This MR removes the ce: and ee: prefix as the job names do not have this in InfluxDB.
