rustdoc: remove no-op CSS `#settings-menu { padding: 0 }`

This CSS was added in 5e01ba3, and served to override CSS right above it that set a 5px padding for several kinds of buttons in the same toolbar:

https://github.com/rust-lang/rust/blob/5e01ba36c9f1037c4cf3e7421413fc6c41f85d05/src/librustdoc/html/static/css/rustdoc.css#L1400-L1409

The CSS that it overrode is still there, but now it only applies to `#settings-menu > a`, so there's nothing to override.
