bug#26587: 26.0.50; Gnus signs with false S/MIME key

[Torsten Bronger]

If I have keys for different email addresses in my gpgsm keyring, Gnus
signs an outgoing email using S/MIME with the first one listed by "gpgsm
--list-secret-keys" instead of the one actually associated with the
"From:" mail address.
