package: OFFICE-3940 ODF 1.3 import of OpenPGP encryption

This was supposed to be implemented by commit
a7bf6488ebb544e1efaed0a1e53073df9cc2064d
"ODF1.3: import new OpenPGP encryption markup"
but it turns out that the ODF 1.3 cs01 schema differs from the
implementation:

in ODF 1.3 cs01 we have

 <manifest:encrypted-key>
  <manifest:encryption-method .../>
  <manifest:keyinfo>
    <manifest:PGPData>
    </manifest:PGPData>
  </manifest:keyinfo>
  <manifest:CipherData>
  </manifest:CipherData>
 </manifest:encrypted-key>

whereas the implementation expects

 <manifest:keyinfo>
  <manifest:encrypted-key>
   <manifest:encryption-method .../>
    <manifest:PGPData>
    </manifest:PGPData>
   <manifest:CipherData>
   </manifest:CipherData>
  </manifest:encrypted-key>
 </manifest:keyinfo>

Ideally the inner manifest:keyinfo should be manifest:KeyInfo but
not sure if that really matters.
