wasmtime cranelift log pollutes the containerd log

## Reproduce

Run containerd locally by running `make` and then `./bin/containerd --log-level debug` in root user. Then invokes the wasmtime shim to execute the demo wasm container: `sudo ctr run --rm --runtime=io.containerd.wasmtime.v1 ghcr.io/containerd/runwasi/wasi-demo-app:latest testwasm`, then you will see something like:


## Expected

We should by default turn off cranelift logs as these are low-level compiler logs which don't fit into operational logs like containerd.
