8276657: XSLT compiler tries to define a class with empty name

[JoeWang-Java]

The result of Util.baseName(systemId) can be empty, causing the compiler to set an empty classname. Add a check to make sure it will not set the empty classname.

Alternatively, it may report an error, but that would be disruptive. As the transform can proceed without the provided classname (by using the default), adding a check is better than reporting an error.

I've verified the patch with the proposed fix for JDK-8276241. Harold has also confirmed it fixes the tests in his builds.
