This commit enables the support added in #7070 by default. This means that gradually over time all `Cargo.lock` files will be migrated to the new format. Cargo shipped with Rust 1.38.0 supports this new lock file format, so any project using Rust 1.38.0 or above will converge quickly onto the new lock file format and continue working. The main benefit of the new format is to be more friendly to git merge conflicts. Information is deduplicated throughout the lock file to avoid verbose `depedencies` lists and the `checksum` data is all listed inline with `[[package]]`. This has been deployed with rust-lang/rust for some time now and it subjectively at least seems to have greatly reduced the amount of bouncing that happens for touching `Cargo.lock`.
