The seccomp events are very useful for people who are working with seccomp 
filters and I want to ensure that we have the ability to emit these events 
regardless of if audit is enabled, or even compiled into the kernel using 
dmesg/syslog as we do today with other auditable events, e.g. SELinux.

Because of this desire to log regardless of audit, I figured a sysctl tunable 
made more sense than an audit based filter.  As I mentioned previously, I'm 
not completely sold on the sysctl based solution, but it is the best solution 
that I can think of at the moment.  Alternatives are welcome.
