RFR(xs): 8154204: [TESTBUG] Update DefaultUseWithClient test to handle client-less builds

[Calvin Cheung]

JBS: https://bugs.openjdk.java.net/browse/JDK-8154204

webrev: http://cr.openjdk.java.net/~ccheung/8154204/webrev.00/

The DefaultUseWithClient.java test was designed for testing only windows 
32-bit.
Since we no longer support windows 32-bit, the change is simply removing 
the test and the references to it in other files.

(I think it is considered a trivial change.)

Testing: (on Oracle platforms)
     hs-tier{1,2}
