KingIcyCreamProjects 51dd4805af benchmark_cuda_fixture: accept the current PROFILE service/wait format
profile_print now emits 'expert-disk N.NNNs service / N.NNNs wait' but
the harness regex still expected the old single expert-disk number, so
every run died with 'benchmark output missing'. Accept both formats and
report disk = service + wait.
