audit: build with libcap_ng

See auditd-plugins(5) for motivation:
> When the audit daemon starts your plugin, you will be running as root.
> If you do not need root privileges, you should change uid/gid to lower
> chances of being a target for exploit. If you need to retain capabilities,
> using libcap-ng is the simplest way.

`libcap_ng` is already in the closure via util-linux and thus does not
unnecessarily bloat the system. It is also a very sane idea to allow
plugins to drop privileges if they already conveniently support it.
