Allow to export private keys.

Browse Source 
Using a workaround that validates passphrase for a secret key.

With GnuPG 2.2.23 and GpgME 1.1.15, a secret key can be exported when the right
passphrase is provided. With a bad passphrase, application crashes.

See https://dev.gnupg.org/T5151

Application may validate a passphrase before invoking engine. Until it is
hopefully fixed in upstream and available in mainstream.
