[PyTorch] Fix bin hash comparison failure in clang format script (#55281)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/55281
## Summary
` python3 tools/clang_format_all.py` is complaining that binary is not what expected. Find out the reference hash include an extra new line comparing with the actual hash. In this pr,
1. Use `expr(hash)` to show the raw string, such that it's easier to compare two string.
2. Remove the extra new line.
3. Run `python3 tools/clang_format_all.py `, and it formats `torch/csrc/jit/runtime/static/passes.h`.
Before the change,
```
(base) chenlai@chenlai-mp pytorch % python3 tools/clang_format_all.py -v
Found pre-existing clang-format binary, skipping download
Reference Hash: '5fde7bccf65032da297dfb1f18e4a95e96e278fa397e9dcaf364dfe23ec46353'
Actual Hash: '5fde7bccf65032da297dfb1f18e4a95e96e278fa397e9dcaf364dfe23ec46353'
The downloaded binary is not what was expected!

After strip the hash str:
