Disambiguate benchmarks directory search.

[ysiraichi]

Follow-up: #6428

This PR disambiguates pytorch/benchmarks directory from xla/benchmarks directory. In order to do that without relying on the name of the directory that the repo lives, we look for benchmarks/dynamo, instead. Works, since the dynamo directory only exists on pytorch/benchmarks.

Thanks, LGTM!

Oh, just noticed that it is still unable to find the benchmarks/dynamo, because the file is under pytorch/. Let's add 'pytorch/benchmarks' instead... Let me revert this one for now.

@zpcore Interesting. How are the repos (PyTorch and PyTorch/XLA) organized in CI (or wherever you are trying to run the benchmarks)?

[zpcore]

Hi @ysiraichi , I tried the following organization:

|--pytorch
|  --benchmarks
|     --dynamo
|     --...
|--xla
|  --benchmarks  <- I am running under this folder
|      -- 

In this case, it will not search under pytorch folder.

[ysiraichi]

Hmm... I see. What do you say we leave both of them: ("benchmarks/dynamo", "pytorch/benchmarks")?

[zpcore]

Yes, this should also work. Thanks!
