Fix flaky issues on MacOS CI (buck2, libzstd) (#200)

Summary:
Here are some flaky issue on MacOS CI that I have seen:

* https://github.com/pytorch/executorch/actions/runs/6053110980/job/16428034274 with `dyld[68891]: Library not loaded: rpath/libzstd.1.dylib` error.  This is the same issue happening on PyTorch, so I copy the fix there in the `print_cmake_info` function
* Buck build fails on MacOS.  I'm not sure the reason here but retry probably works:
  * https://github.com/pytorch/executorch/actions/runs/6029912472/job/16360557094 with `Failed to connect to buck daemon`
  * https://github.com/pytorch/executorch/actions/runs/6052938317/job/16427461951 with some internal errors with `write_file`
