Add a num_online_cpus() check to test_race_signal_callback() as the default kunit.py runs the VM with a single CPU and this test depends on two truly parallel kthreads. Skip it instead of hanging.

The kunit tool can be used to build a kernel and run it in a VM with: $ tools/testing/kunit/kunit.py run --build_dir build_kunit_x86_64 --arch x86_64 --kunitconfig ./drivers/dma-buf/.kunitconfig Along with the other ways to run kunits. To make the kunit tool work like this the DMABUF_KUNIT_TEST kconfig must select DMA_SHARED_BUFFER to get it turned on without building a driver using it.
