UV_USE_IO_URING does not update file handle position

[ronag]

I suspect possible regression. Not sure what version but must have been recent:

await stream.promises.pipeline(src, fs.createWriteStream(dstPath))

Will not create a full sized file. I suspect that since createWriteStream doesn't explicitly set position during writes it expects the file handle position to be properly updated, which does not seem to be the case with URING.
