rustdoc: simplify `.search-results-title` CSS

By using `display: flex`, we still get the never-wrapping layout with `#crate-search-div` maxing out and truncating its text. The title itself winds up always filling its parent, but since `#crate-search` doesn't have `flex-grow` set, it won't fill available space.
