Rust plugin always installs the rustup snap, even when trying to use local cargo/rustc
Metadata
Current evaluation
Rust-plugin rustup installation report was closed without a recorded fix, replacement, or explanation; the sole comment only sought maintainer assignment.
Resolution: closed stale
Reason: The issue tracker records no resolving PR, commit, or superseding work. The only maintainer comment, posted on 2024-11-12, merely attempted to assign another maintainer, so closure appears to reflect abandonment or inactivity.

### Bug Description
Rustup always gets installed, even if we're trying to use local `cargo` and `rustc` installed from another part.
### To Reproduce
Build with the following part
### part yaml
```shell
parts:
rust-deps:
plugin: nil
build-packages:
- librust-indexmap-dev
- librust-itoa-dev
- librust-memchr-dev
- librust-ryu-dev
- librust-serde-dev
- cargo
- cargo-1.80
override-pull: |
ln -s /bin/cargo-1.80 /usr/local/bin/cargo
ln -s /bin/rustc-1.80 /usr/local/bin/rustc
librust-serde-json:
plugin: rust
after: [rust-deps]
source: .
```
