Fix libc-wasi not working in spawned exec_env (#1053)

Browse Source 
In thread_manager.c, `wasm_cluster_spawn_exec_env` creates a new module
instance but not sets wasi_ctx, so when the new exec_env calls wasm function
which uses WASI API, the WASI API functions in `libc_wasi_wrapper.c` will get
null result in calling `get_wasi_ctx`  and then return `wasi_errno`.
