Summary:
Adds the ability to receive seccomp notify events from a process asynchronously.
NOTE: Getting the file descriptor out of the `seccomp()` return value in the child process is very akward. Because of this, there is currently a possibility of deadlock if using `seccomp_notify` and a process fails to spawn. In this case, an error will be sent through a pipe to the parent process, but the parent process will never be able to read it because it will be spinning in a loop trying to read the file descriptor from the child.
