evil_string: fix strndup() for non-NULL terminated strings.devs/barbieri/efl_net_socket_windows2
If the given string is not null-terminated, then strlen() will go out
of boundaries, we must limit the lookup to given 'n' parameter.
To do so use strnlen(), that is a strlen() bounded by a maximum size.
