Fix widespread leak in the sendsig_siginfo() functions. sigframe_siginfo
has padding, so zero it out properly. 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.
