RFR: 8343316: Review and update tests using explicit provider names

[Matthew Donovan]

In this PR, I updated a few crypto tests to remove the hard-coded provider name and use the `test.provider.name` property instead. These tests were missed while working on [JDK-8341927](https://bugs.openjdk.org/browse/JDK-8341927).
