* scd/app-piv.c (PIV_ALGORITHM_RSA): Rename to PIV_ALGORITHM_RSA_2048.
(PIV_ALGORITHM_RSA_3072): New.
(get_key_algorithm_by_dobj): Decide whether to use 3072 or 2048.
(do_sign): Support rsa3072.
(do_decipher): Ditto.
(do_genkey): Ditto.

Take care: Due to a lack of a PIV token capable of 3072, this has
not been tested at all.
