lib: Use new kselftest header
We just added a new C header file for use with test modules that are intended to be run with kselftest. We can reduce code duplication by using this header. Use new kselftest header to reduce code duplication in test_printf and test_bitmap test modules. Acked-by: Kees Cook <keescook@chromium.org> Signed-off-by: Tobin C. Harding <tobin@kernel.org> Signed-off-by: Shuah Khan <shuah@kernel.org>
