Waste of space, at least on a 32 bit machine where the size of the ipc
aux data is definitely larger than the sockcall aux data. But I guess
what you did is a whole lot easier and clearer than to try to hack up
adding it to both sockcall and new pipe_fds and using the right one at
the right time. I guess if we cared about 64 bits per audited thread we
wouldn't be moving the aux data into the audit_context anyway.
