Address vulnerabilities reported within the tools directory (#2633)

## Motivation and Context
Addresses vulnerabilities reported by `cargo audit` within the
repository.

## Description
This commit addresses vulnerabilities within the tools directory
reported by `cargo audit`. Mostly they have been fixed by regenerating
`Cargo.lock` files. Two exceptions:
- `crate-hasher` needs to drop the `temp_dir` crate and switch over to
the `tempfile` crate
- `canary-runner` needs to upgrade the `octorust` crate

## Testing
After the PR, no vulnerabilities reported from the crates that have been
patched. Ran `cargo t` on the updated crates.
Furthermore, no vulnerabilities reported currently within `rust-runtime`
and `aws/rust-runtime`:
