sylpheed: patch to use SNI

Prior to this patch, sylpheed built against newer versions of LibreSSL could
not connect to IMAP server such as gmail's because it did not use SNI. This
patch from OpenBSD is a simple fix to implement it.

This patch is also necessary with OpenSSL.

Also xlint template.

Closes: #23487 [via git-merge-pr]
