Subject: [PATCH 2/5] kunit: kunit-test: Remove stub for log tests

Since now we are exporting string-stream functions into the KUnit
namespace, we can safely use them in kunit-test when it is compiled as
a module as well. So, remove the stubs used when kunit-test is compiled
as a module. Import the KUnit namespace in the test.
