    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.
    
    Fixes bug 21943; bugfix on 0.2.5.1-alpha when the sandbox was
    introduced.
