scd:p15: Fix decrypt followed by sign problem for D-Trust cards.

Browse source 
* scd/iso7816.c (iso7816_select_mf): New.
* scd/app-p15.c (card_product_t): New.
(struct app_local_s): Add field 'card_product'.
(read_ef_tokeninfo): Detect D-Trust card.
(prepare_verify_pin): Switch to D-Trust AID.
(do_decipher): Restore a SE for D-TRust cards.  Chnage the passing
indicator to 0x81.

Using what I learned from a USB trace running the Governikus Signer
Software on Windows this fixes the left over problem with the new
D-Trust card support.
