[jdk17] RFR: 8271174: runtime/ClassFile/UnsupportedClassFileVersion.java can be run in driver mode

[Igor Ignatyev]

Hi all,

could you please review this trivial patch that switches execution mode in `runtime/ClassFile/UnsupportedClassFileVersion.java` test to `driver`?

testing: `runtime/ClassFile/UnsupportedClassFileVersion.java` on `{linux,windows,macos}-x64`

Thanks,
-- Igor
