card: List more info for an OpenPGP key.

Browse Source 
* tools/gpg-card.h (struct pubkey_s): Add field created.
* tools/card-keys.c (parse_key_record): Set that field.
* tools/gpg-card.c (print_shax_fpr): Print the fingerprint without
spaces for easier c+p.
(list_one_kinfo): Print the actual used fingerprint and creation date
from the keyblock.
--

A common problem with OpenPGP cards is that the fingerprint as stored
on the card does not match the actual fingerprint.  Print both values
to be able to investigate such issues.
