Subject: [PATCH] src/runtime: add stub for runtime.NumCPU()

This adds a stub for the `NumCPU()` function from the `runtime`
package.
This change allows code to compile that tries to access this function.

I guess for most hardware boards and WASM setting this value to `1` is
fine. And as far as I can see it shouldn't break or change existing
applications, because the function previously did not exist at all.
