Rename classesByName2Test to jdk_classesByName2Test

[LongyuZhang]

Rerun of this test got skipped since rerun target is based on name.

Issue: ibm_git/runtimes/automation/issues/204

Test Link:

• hyc-grinder 49010 to generate the failed pipeline, the Rerun failed jdk test cases in Grinder with jdk_custom target will then rerun with jdk_custom.

just for the record, OpenJDK test target names are expected to have a certain format to run with the correct custom target (in auto-rerun):

We expect to have a couple more test target name updates as we go through the existing ones.

@LongyuZhang could you update the doc for the expected naming format if we haven't done so? Thanks
