rust: kbuild: run Clippy for `rusttest` code
Running Clippy for `rusttest` code is useful to catch issues there too, even if the code is not as critical. In the future, this code may also run in kernelspace and could be copy-pasted. Thus it is useful to keep it under the same standards. For instance, it will now make us add `// SAFETY` comments. It also makes everything more consistent. Thus clean the few issues spotted by Clippy and start running it.
