Merge rayon-rs#705

705: Update compat-Cargo.lock r=cuviper a=matklad

I've noticed that rayon-rs#704 uses old compat lockfile, which is strange, given that it changes Cargo.lock.

What happens here is that cargo writes new compat lockfile during CI.

That means that CI might break randomly, if rayon's dependency is published with the same major version, but different MSRV

With this PR, CI will break deterministically if you change Cargo.toml and don't update compat-Cargo.lock.

Not sure if this actually makes sense :)
