errors: Use `errors.Is()` for `io.EOF` errors

Replace all io.EOF errors comparisons with errors.Is(). This ensures
that these errors work correctly with wrapped errors. This also makes
way for adding an error linter in the upcoming commits.

The changes in this commit were done automagically using project wide
replace methods provided by the text editor.
