gpg: Set the node flags while retrieving a keyblock.

* g10/keydb.c (parse_keyblock_image): Add args PK_NO and UID_NO and
set the note flags accordingly.
(keydb_get_keyblock): Transfer PK_NO and UID_NO to parse_keyblock_image.
* kbx/keybox-search.c (blob_cmp_fpr, blob_cmp_fpr_part)
(blob_cmp_name, blob_cmp_mail): Return the key/user number.
(keybox_search): Set the key and user number into the found struct.
(keybox_get_keyblock): Add args R_PK_NO and R_UID_NO and set them from
the found struct.
--

getkey.c needs to know whether the correct subkey was found.  Thus we
need to set the node flags the same way we did it with the keyring
storage.
