[jdk25u] RFR: 8361711: Add library name configurability to PKCS11Test.java

[Thomas Fitzsimmons]

Hi all,

This pull request contains a backport of commit [1cb1267c](https://github.com/openjdk/jdk/commit/1cb1267ce84dea2bfcb434b03c982b859997c6d2) from the [openjdk/jdk](https://git.openjdk.org/jdk) repository.

The commit being backported was authored by Thomas Fitzsimmons on 15 Sep 2025 and was reviewed by Valerie Peng.

This backport will allow the Kryoptic continuous integration scripts to test against upstream OpenJDK 25.  I have this patch working with Kryoptic CI (merged in https://github.com/latchset/kryoptic/pull/347) in a branch of my own jdk25u fork (https://github.com/fitzsim/jdk25u/tree/kryoptic-jdk-25).

Thanks!
