Adds Rust support for ARM64 architecture

Enables Rust compilation for ARM64 architecture in the CI light Dockerfile.

This change adds the necessary dependencies and configuration to build Rust-based projects on ARM64 platforms within the CI environment. It specifically installs `curl`, `libgcc`, `build-base`, and `musl-dev` and uses `rustup` to manage rust installations if the target platform is `linux/arm64`.
