tools: Add new "test" taint to kernel-chktaint
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. With this change the correct reason will be reported if the kernel is tainted because of a test run.
