t/unit-tests: update clar to 16e7966

Hi,

this updates us to the latest version of clar. Most of the changes are somewhat uninteresting to us, but this contains the fixes for HP-UX.

Junio, I was wondering whether we also want to do this similarly to how you handle the gitk/git-gui pull requests. I ultimately don't mind it much though, so I'm also happy to do this with "normal" patch series.

Thanks!

Patrick
