qemu_v8: Enable Rust examples build by default

With no-std support it has significantly reduced time to build and test
rust examples. So enable rust examples build by default for qemu_v8.
Along with that add rust expect script to build repo to avoid
check script duplication in OP-TEE rust SDK repo.
