add --force, it's installed somewhere

[TriplEight]

it appeared that cargo audit was installed previously, that failed the beta and stable builds:

cargo-audit v0.5.2
error: binary `cargo-audit` already exists in destination as part of `cargo-audit v0.5.2`
Add --force to overwrite

I think we don't need it on master, since we've removed caches in #9855, so we either backport this or that PR.

I support @ordian opinion on this topic.
