NetLabel: honor the audit_enabled flag
The audit_enabled flag is used to signal when syscall auditing is to be
performed. While NetLabel uses a Netlink interface instead of syscalls, it is
reasonable to consider the NetLabel Netlink interface as a form of syscall so
pay attention to the audit_enabled flag when generating audit messages in
NetLabel.
