Remove superfluous @test tags from SpliteratorTraversingAndSplittingTest

[Jonathan Gibbons]

Chris,

It might point to a bug in jtreg, or just "bad" jtreg meta-data.
  >: ls one
.                ..               HelloWorld.java
  >: cat one/HelloWorld.java
/*
   * @test
   * @bug 8765432
   */

/*
   * @test
   */

public class HelloWorld {
      public static void main(String[] args) {
          System.out.println("Hello World.");
      }
}

This is a un-feature in jtreg.   Strictly speaking, the jtreg Tag Spec 
only allows one test description per file, and so if you follow the 
spec, the situation you describe cannot arise.
