gpg: Make --export-options work with --export-secret-keys.

* g10/export.c (export_seckeys): Add arg OPTIONS and pass it to
do_export.
(export_secsubkeys): Ditto.
* g10/gpg.c (main): Pass opt.export_options to export_seckeys and
export_secsubkeys
--

Back in the old days we did not used the export options for secret
keys export because of a lot of duplicated code and that the old
secring.gpg was anyway smaller that the pubring.gpg.  With 2.1 it was
pretty easy to enable it.
