[clang-tidy] Replace unrecognized namespace ending comments.

Summary:
Replace unrecognized namespace ending comments. This will help in particular when a namespace ending comment is mistyped or doesn't fit the regexp for other reason, e.g.:

  namespace a {
  namespace b {
  namespace {
  } // anoynmous namespace
  } // b
  } // namesapce a
