scd: Allow standard keyref scheme for app-openpgp.

Browse source 
* scd/app-openpgp.c (do_change_pin): Allow prefixing the CHVNO with
"OPENPGP."

is send to a wrong card.  This has been taken from master commit
3231ecdafd which has additional changed
for gpg-card-tool, which is only available there.
