message: Don't create a duplicate title on rustdoc pages

  docs.rs title. We should only show the rustdoc title.
diff: <link rel="stylesheet" href="/style.css?{{ docsrs_version() | slugify }}" type="text/css" media="all" />
  <link rel="search" href="/opensearch.xml" type="application/opensearchdescription+xml" title="Docs.rs">
  -
  - <title>{{ macros::doc_title(name=krate.name, version=krate.version) }}</title>
