Revert "job: Don't mark as redundant if deps are relevant"

This reverts commit 097537f07a.

At least Fedora and Debian have already reverted this at the distro
level because it causes more problems than it solves. Arch is debating
reverting it as well [0] but would strongly prefer that this happens
upstream first. Fixes #15188.
