Fix a bug in cpu userbenchmark with launcher (#1650)
Summary:
Works for https://github.com/pytorch/benchmark/issues/1293 to enhance the cpu userbenchmark with launcher.
Fixes https://github.com/pytorch/benchmark/issues/1649
Before:
```shell
$ python run_benchmark.py cpu -m resnet50 --launcher --launcher-args=" --throughput-mode"
Running benchmark: /localdisk/chuanqiw/miniconda3/envs/torchdynamo/bin/python -m torch.backends.xeon.run_cpu --throughput-mode /localdisk/chuanqiw/PT/benchmark/userbenchmark/cpu/run_config.py -m resnet50 --device cpu -t eval -o /localdisk/chuanqiw/PT/benchmark/.userbenchmark/cpu/cpu-20230514213153
Traceback (most recent call last):

```
After:
```shell
$ python run_benchmark.py cpu -m resnet50 --launcher --launcher-args=" --throughput-mode"
