Implement sock_addr_remote syscall (#1360)

Browse Source 
Slightly changed the interface sock_addr_remote - since we already
have a `__wasi_addr_t` structure which is an union, there's no need
for passing length around - the address buffer will always have the
right length (i.e. max of all address families).
