permission-find missed some results with --pkey-only option

When permission-find post callback detected a --pkey-only option,
it just terminated. However, this way the results that could have
been added from aci_find matches were not included.

Fix the post callback to go through the entire matching process.
Also make sure that DNS permissions have a correct objectclass
(ipapermission), otherwise such objects are not matched by the
permission LDAP search.
