Run cargo audit on committed Cargo.lock

The current audit action regenerates the lock file which may hide
vulnerabilities in our binaries.

Ensure binaries are built with committed lock file by adding the
`--locked` flag. Note the `--locked` flag is currently documented in a
confusing way in `cargo --help`.

A fix for that has been merged into cargo recently:

rust-lang/cargo#13665
