ci: build for WebAssembly in CI

`vapor/ci`'s reusable unit-test workflow already knows how to build a package
for `wasm32-unknown-wasip1`; sqlite-kit simply had not opted in. Turn the lane
on so the SwiftNIO-free path cannot regress unnoticed.

sql-kit already passes `with_wasm: true` to the same workflow.
