inet: fix getservbyname buffer overflow
The byte holding the length of the interface name for the getservbyname/2 function is used in a signed context and can become negative, causing the buffer to be overrun. Make the same change for getservbyport/2. Test case: inet:getservbyname(list_to_atom(lists:flatten(lists:duplicate(128, "x"))), tcp).
