Pull request overview

This PR merges forward Jammy changes into the Noble branch, updating the Jammy OS image references and aligning auditd-related build/test behavior with the distro-provided systemd unit.

Changes:

• Remove the build-time override of auditd.service and rely on the packaged unit file under /lib/systemd/system.
• Bump the Jammy metalink to 1080.0.0 with updated hashes/sizes.
• Update Jammy OS image specs to validate auditd’s systemd unit location/content (but one new assertion currently checks the wrong filesystem).
