ZSKs sign some RRsets but not others

Nothing wrong here.  The A RRset will be signed with the new key
when it falls due for re-signing as there is a existing RRSIG using
algorithm 8.  The SOA was signed as the DNSKEY was added which
required the SOA to be updated as well.

You can force named to re-sign all the RRsets but there is no need
to do that.
