rust: disable stack probes

We do not support function-call stack probes, and LLVM inline asm stack
probe is currently broken [1][2]. Switching target's `stack-probes`
to "none" allows us to avoid broken codegen and the intrinsic call.
We could switch the `stack-probes` property to `inline` if we want once
the LLVM codegen issue is resolved.
