rustc: build with jemalloc

[misuzu]

Motivation for this change

I have to run cargo build several times to build something on macOS, rustc randomly fails with SIGABRT.
This change fixes the issue for me.

The official Rust build uses jemalloc on aarch64-darwin (https://github.com/rust-lang/rust/blob/acbe4443cc4c9695c0b74a7b64b60333c990a400/src/ci/github-actions/ci.yml#L456). I am a little concerned by nixpkgs still not using jemalloc on aarch64-darwin.

We could also switch on aarch64 as well.
