[OE-core][PATCH 3/3] oeqa/sdk/rust: Add build and run test of rust binary with SDK host

[Sean Nyekjaer <sean@geanix.com>]

Add a QA test to the SDK to test that a basic cargo build works for the
SDK host.

I know that `cargo build` and `cargo run` is kinda redundant for the `cargo
run` command. But I guess it's easier to see whats happening here...
