card: Allow listing of NKS cards.

* tools/card-call-scd.c (learn_status_cb): Always fill chvinfo.
* tools/gpg-card.h (struct card_info_s): Increase size of chvinfo and
chvmaxlen.
* tools/gpg-card.c (list_nks): New.
(print_a_version): Support single part version numbers.
(list_card): Call list_nks.
--

Note that chvmaxlen is not yet used with NKS.
