The trick I did to make it work is to add a dummy attribute and add another interface, 



interface(`unconfined_domain',`
	gen_require(`
		attribute unconfined_services;
	')	
	unconfined_domain_noaudit($1)
}

unconfined_domain_noaudit has all the rules required for unconfined_domain.

unconfined_domain_noaudit(unconfined_t)
unconfined_domain_noaudit(kernel_t)
unconfined_domain_noaudit(rpm_t)

unconfined_domain(init_t)
unconfined_domain(initrc_t)
...

The only thing in unconfined.te is

policy_module(unconfined, 3.0.1)
