benchmarks/torchbench_model: skip benchmarks that fail to load (#6199)
In "dfcf306e7 Apply precision config env vars in the root process. (#6152)"
we started running load_benchmark() from experiment_runner's
main process. Unfortunately, load_benchmark() for
some models does exit the calling process, which results
in experiment_runner exiting prematurely.
Work around this issue by adding these models to the deny list,
so that experiment_runner does not die early.
