scd:openpgp: Return key creation time as part of KEYPARIINFO.
* scd/app-openpgp.c (send_keypair_info): Reaturn the key creation time as part of a KEYPAIRINFO. (do_readkey): Do not return the KEY-TIME anymore. -- Sending the KEY_TIME status as part of a READKEY command was only recently added. It is better to merge that into the KEYPAIRINFO line. Another patch with chnage this for the consumers of that info. Signed-off-by: Werner Koch <wk@gnupg.org>

*** KEYPAIRINFO <grip> <keyref> [<usage>] [<keytime>]

This status is emitted by scdaemon and gpg-agent to convey brief

<keyref> is the ID of a card's key; for example "OPENPGP.2" for

the second key slot of an OpenPGP card. <usage> is optional and

returns technically possible key usages, this is a string of

single letters describing the usage ('c' for certify, 'e' for

encryption, 's' for signing, 'a' for authentication). A '-' can be

used to tell that usage flags are not conveyed. <keytime> is used

by OpenPGP cards for the stored key creation time. A '-' means no
