Subject: [PATCH] Add some more subpacket types to the list to ignore

  There are various signature subpacket types we know about, but have
  no need to decode (or it doesn't make sense to decode if we're not
  checking that the signature is valid). Add some more to prevent
  warnings when adding keys that have these subpackets present.
