Subject: [PATCH 2/2] kunit: no longer call module_info(test, "Y") for kunit modules

Because KUnit test execution is not a guarantee with the kunit.enable
parameter we want to be careful to only taint the kernel only if an
actual test runs. Calling module_info(test, "Y") for every KUnit module
automatically causes the kernel to be tainted upon module load. Therefore,
we're removing this call and relying on the KUnit framework to taint the
kernel or not.
