After investigation ScanCode-toolkit is failing (timeout) on this file `systemd-252/test/fuzz/fuzz-unit-file/oss-fuzz-8827`
[oss-fuzz-8827.zip](https://github.com/nexB/scancode.io/files/9954307/oss-fuzz-8827.zip)

On the ScanCode.io, we should improve the reporting on those type of failure (hard to catch as long as we use subprocess in the `scan_package` pipeline)

A proper fix is also required on the toolkit side, it's a made up fuzz text for testing and it's rather small, it should not reach the 1h timeout during scanning.
