tools: Add new "test" taint to kernel-chktaint

Commit c272612cb4 ("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.
