What this PR does:
We are currently chasing a very rare panic that occurs in parquet-go. While fixing a related issue in compactors I noticed that io.EOF was not being handled correctly in readers.go. This change makes the various ReaderAt's in vParquet4 handle io.EOF correctly.
It's possible that this change fixes the panic but I believe it to be unlikely.
Also removed the error wrapping in s3.go to be consistent with other backends.
