signal: Add TRAP_UNK si_code for undiagnosted trap exceptions
Both powerpc and alpha have cases where they wronly set si_code to 0 in combination with SIGTRAP and don't mean SI_USER. About half the time this is because the architecture can not report accurately what kind of trap exception triggered the trap exception. The other half the time it looks like no one has bothered to figure out an appropriate si_code. For the cases where the architecture does not have enough information or is too lazy to figure out exactly what kind of trap exception it is define TRAP_UNK.
