When I looked to sanity check that https://github.com/mongodb/bson-rust/pull/483 hadn't caused a regression I discovered to my dismay that the whole benchmark suite has been broken since 3.0 :(
This PR fixes compilation, but the actual server-connecting benchmarks are still broken, I filed RUST-1997 for that.
