Create a new audit record AUDIT_CONTAINER_INFO to document the container
ID of a process if it is present.

Called from audit_log_exit(), syscalls are covered.

A sample raw event:

As mentioned in a previous email, I think AUDIT_CONTAINER is more
suitable for the container record. One more comment below...

Would there be any problem moving audit_log_container_info before
audit_log_proctitle? There are some assumptions that proctitle is the
last record in some situations.
