m68k/mac: Don't hang waiting for Cuda power-down command
Testing shows that the CUDA_POWERDOWN command never completes (for a Centris 660av or LC 475, at least). So, don't wait for command completion on those Cuda-based models that do not support soft power. Just proceed to log the usual message, "It is now safe to turn off your Macintosh."
