* Fix the tests to run on 1.48. This puts the benchmarks behind a `criterion` cfg, so add `--cfg=criterion` to RUSTFLAGS when running cargo bench. An MSRV of 1.48 enables us to support users such as async-io, which also has an MSRV of 1.48. * Add a rust-version field. This prints a warning under Rust 1.48, but only when rustix is the top-level build; when rustix is a dependency, it doesn't warn, so this seems ok.
