ktrace: Log the code for all signals (PSIG events).

Browse Source 
The code provides information on how the signal was generated.

Formerly, the code was only logged for traps, much like only signal handlers
for traps received a meaningful si_code before FreeBSD 7.0.

In rare cases, no information is available and 0 is still logged.
