Tests: Teach CudaOnly.CUBIN to tolerate toolkit not supporting native arch

Since commit 2def6a874b (CUDA: Add support for CUBIN, FATBIN, and
OPTIXIR compilation, 2023-01-27) added this test, it has failed when
executed with a CUDA toolkit that does not support the true native
architecture of the GPU.  Detect this case and skip the test.
