include a siginfo_t with ktrace PSIG information, so that kdump can print
fault addresses and other information. (a small bug exists: in some signal
delivery cases, two PSIG records may be inserted, because postsig() is
unaware a PSIG record has already been placed. but this small bug can
stay since the siginfo_t information helps us find and fix other bugs)
