Subject: [PATCH] exec.c: Initialize sa_flags passed to sigaction()

Coverity points out that in the user-only version of cpu_abort() we
call sigaction() with a partially initialized struct sigaction
(CID 1005351). Correct the omission.

Backports commit 8347c18506c3f8619527d19134cb4aac071dc54a from qemu
