[cleaner] Regression in hostname cleanup

[arif-ali]

As part of our testing to upload 4.10.0 to Debian, we have now found that the cleaner doesn't clean the hostname in ui.log, sos.log and manifest.josb, especially with the hostname in the filename scenario

below the hostname is autopkgtest

!!! TEST FAILED: hostname not obfuscated in all places !!!

I guess it happens (only) when running sos [collect|report] --clean, right? That way I am really able to reproduce the problem (and I am digging into it).
