[SPARK-49077][SQL][TESTS] Remove bouncycastle-related test dependen…

…cies from `hive-thriftserver` module

### What changes were proposed in this pull request?
After SPARK-49066 merged, other than `OrcEncryptionSuite`, the test cases for writing Orc data no longer require the use of `FakeKeyProvider`. As a result, `hive-thriftserver` no longer needs these test dependencies.

### Why are the changes needed?
Clean up the test dependencies that are no longer needed by `hive-thriftserver`.

No
