send-email: refactor sendemail.smtpencryption config parsing

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.

This gets us rid of an unconditional call to Git::config(), which as
we'll see in subsequent commits matters for startup performance.
