[PATCH 2/2] send-email: refactor sendemail.smtpencryption config parsing

["Ævar Arnfjörð Bjarmason" <avarab@gmail.com>]

With the removal of the support for sendemail.smtpssl in the preceding
commit the parsing of sendemail.smtpencryption is no longer special,
and can by moved to %config_settings.
