sm: Print the key types as standard key algorithm strings.

Browse source 
* sm/fingerprint.c (gpgsm_get_key_algo_info): Factor code out to ...
(gpgsm_get_key_algo_info2): new.
(gpgsm_pubkey_algo_string): New.
* sm/keylist.c (list_cert_colon): Put curve into field 17
(list_cert_raw): Print the unified key algotithm string instead of the
algo and size.
(list_cert_std): Ditto.

It is important to known whether a 256 bit ECC uses a NIST or a
Brainpool curve.
