rustdoc: remove unused CSS `div.impl-items > div`

This was added in 9077d54 to override the style on `<div>` tags that were acting as headers. These `<div>` tags were replaced with `<section>` tags in 32f6260, but this CSS was probably already redundant even then (the headers had already been replaced with real `<h3>` and `<h4>` tags in 76a3b60).
