Splits gb_JunitTest_set_unoapi_test_class_and_jars into two
separate defines as:
- gb_JunitTest_use_unoapi_jars
- gb_JunitTest_use_unoapi_test_class

Then replaces many of the gb_JunitTest_use_jars lists with the
new gb_JunitTest_use_unoapi_jars to fix the JUH dependencies.
This probably adds some unneeded JUH dependencies to some Java
tests, but that shouldn't be a problem.
