Subject: Set the C target to wasm32-wasi rather than wasm32

Set the C target to wasm32-wasi rather than wasm32

We need at least a partial C stdlib anyway, so there's no real
difference going ahead and linking wasm32-wasi on the C side vs
only on the Rust side. This fixes compilation on Debian testing
with OS packages installed.
