Make port broken if openssl version 1.1.0+ is not available

[openiked-portable] / pkg-descr

OpenIKED is a free, permissively licensed Internet Key Exchange
(IKEv2) implementation, developed as part of the OpenBSD project.
It is intended to be a lean, secure and interoperable daemon that
allows for easy setup and management of IPsec VPNs.

The portable versions take
the OpenBSD based source code and add compatibility functions and
build infrastructure for other operating systems.
