RFR: 8325880: Require minimum Open XL C/C++ version 17.1.1

[Kim Barrett]

Please review this change that updates the minimum supported version of IBM
Open XL C/C++.  SAP dropped support for older versions in JDK 22, only
supporting the version specified in this change.

I need someone from the aix-ppc porters to test and review the change.
