Commit c272612cb4a2 ("kunit: Taint the kernel when KUnit tests are run") added a new taint flag for when in-kernel tests run. This commit adds recognition of this new flag in kernel-chktaint.

Changes in v2:
- based off of kselftest/kunit branch
- Added David's Reviewed-by tag
This still looks good to me.
Unless anyone objects, I guess we'll take this through the KUnit branch (which, after all, is where the taint was originally added). I've added it to the list for 6.1, but it technically could be considered a fix for 6.0 as well.
