[tor/release-0.2.9] Add getpid() to the seccomp2 sandbox.

commit 99e943998dcfd1263301224104ef98596325f9f2 Author: Nick Mathewson <nickm(a)torproject.org> Date: Wed Apr 26 12:56:06 2017 -0400 Add getpid() to the seccomp2 sandbox. We hadn't needed this before, because most getpid() callers on Linux were looking at the vDSO version of getpid(). I don't know why at least one version of OpenSSL seems to be ignoring the vDSO, but this change should fix it.
