[Greg Hudson via RT]

Use krb5_expand_hostname() when creating KDB

In kdb5_util's add_admin_princs(), use krb5_expand_hostname() instead
of custom canonicalization code to canonicalize the hostname.  There
are some minor behavior differences:

* Canonicalization will no longer use AI_ADDRCONFIG.
* Canonicalization will use reverse DNS if configuration permits.
* Canonicalization will be affected by the dns_canonicalize_hostname
  and rdns profile variables.
* If name lookup fails, the original hostname will be used.
* A trailing dot will be removed from the name lookup result, if
  present.
