Fix SET_SS_LEN so that it also works correctly outside libratbox. 

Use RB_SOCKADDR_HAS_SA_LEN instead of SOCKADDR_IN_HAS_LEN
which is only defined inside libratbox.
This fixes creating own sockaddr structs in other programs
using SET_SS_LEN, then passing them to libratbox, on
4.4BSD based systems.
