While here I'm also zeroing out some other things in several ports, for safety. Same problem in netbsd32, so fix that too. I can't compile-test on each architecture, but there should be no breakage (tm). Overall this fixes at least 14 info leaks. Prompted by the discovery by KLEAK of a leak in amd64's sendsig_siginfo.
