fix(wamr): Fix networking capability for all platforms (#174)

In instance create, wamr's wasm_runtime_set_wasi_*_pool() functions are storing
addr_pool and ns_lookup_pool as pointers. These variables are lost the moment we
leave the instance create part, and wamr tries to access them afterwards during
the instance execution. We need to store these even if we leave the funtion.
