http_server closes connection when sent list contains an integer

The call `http_server:reply(200, [<<"Hello, world!">>, 34], Conn)` in AtomVM/examples/erlang/system_info_server.erl gives the error `invalid iolist`. The function `interop_iolist_size` in interop.c gives the error InteropBadArg. It seems the function cann't handle integers in iolists.
