The ulib Rust demo requires cross-compilation targets that are not
present in the CI Docker image. Install rustup with the minimal profile
and add the four targets needed by the Rust demo builds:

- i686-unknown-linux-gnu (qemu-x86)
- x86_64-unknown-none (qemu-x86_64, efi-x86_app64)
- riscv64gc-unknown-none-elf (qemu-riscv64, efi-riscv_app64)
- aarch64-unknown-none (efi-arm_app64)
