[PATCH] (GnupG 2.0) g10: fix --card-status creating stub.

[NIIBE Yutaka]

Hello,

This is a simple fix against the issue reported to gnupg-users:

    https://lists.gnupg.org/pipermail/gnupg-users/2015-July/053993.html

The fix is that it should search exact match of secret key.

The specific function get_seckeyblock_byfprint is only used by the
particular calls in the card_status function in g10/card-util.c.  So,
I think that there will be no impact other than --card-status itself.

I'll push this.
