Subject: [PATCH] Properly initialize sigaction struct

The code in skynet_main.c wasn't clearing the struct sigaction before passing it to sigaction().
This meant that we would block a random set of signals while executing the SIGPIPE handler, or jump to the uninitialized __sa_sigaction__ (instead of sa_handler).
Initialize properly as we do in skynet_start.c.
