sysutils/ipmitool: unbreak with openssl 1.1.1 import

• Only apply openssl patch if we are on a version of FreeBSD with openssl 1.1.1
• Don't bump portrevision as we don't change anything except on broken systems

It should be noted that this is a functional way to fix this port and is the method
used upstream. There are most likely better ways to do this.
