fix(entrypoint.sh): Avoid error if rustup is not installed

Browse Source 
Only move `/root/.rustup` and `/root/.cargo` directories if they exist.
This prevents errors when re-using the script in environments where
Rust is not installed (e.g. https://github.com/dockbuild/dockbuild).

Previously, `mv` would fail if either directory was missing:

```
mv: cannot stat '/root/.rustup': No such file or directory
mv: cannot stat '/root/.cargo': No such file or directory
```
