Fails to copy build-info.cpp on windows

[torkleyy]

This seems already specifically addressed in build.rs:

https://github.com/utilityai/llama-cpp-rs/blob/541254585b1e69ed134e4ca01a0c76de7527458a/llama-cpp-sys-2/build.rs#L379C5-L388C8

However, in my case the copy also failed with:

Os { code: 32, kind: Uncategorized, message: "The process cannot access the file because it is being used by another process." }
