commit 11c6c5099fb750e90f7ecdeb901897f3b184a714

Make sure that sigaction always starts zeroed
On some systems, stapsh's child process was getting automatically
reaped, which caused an error when we tried to waitpid(). This was
because we weren't fully zeroing the sigaction, so sa_flags was
uninitialized (and happened to contain SA_NOCLDWAIT).
This patch sprinkles memset-0 on sigactions throughout.
