This commit updates all `err == io.EOF` comparisons to use
`errors.Is(err, io.EOF)`. This is necessary when the error may have been
wrapped and fixes at least one current breakage (in `tsh request ls`).
`golang.org/x/tools/refactor/eg` was very handy for this, I used the
following template:
```go
package teleport
import (
"errors"
"io"
)
func before(err error) bool { return err == io.EOF }
func after(err error) bool { return errors.Is(err, io.EOF) }
```
