This reverts commit d4951968f0, #10008.
When Forgejo cancels a job server-side, for example due to an additional push to an open PR, it immediately archives the logs from DBFS to disk due to the changes in #10008. Then, the runner recognizes that the job status is cancelled and it attempts to flush its pending logs to Forgejo, resulting in warnings being logged:
```

This appears to be the cause of the `push-cancel` end-to-end test failing since #10008 was merged. https://code.forgejo.org/forgejo/end-to-end/actions/runs/4985/jobs/8/attempt/1 The `push-cancel` test case itself seems to succeed, but then the test process aborts with `return 1`. Doesn't reproduce locally.
