RFR(T) : 8252532 : use Utils.TEST_NATIVE_PATH instead of System.getProperty("test.nativepath")

[Igor Ignatyev]

Hi Serguei, David,

thanks for your reviews, I've updated the patch to address David's comments:
 http://cr.openjdk.java.net/~iignatyev//8252532/webrev.01/ <http://cr.openjdk.java.net/~iignatyev//8252532/webrev.01/> (whole)
 http://cr.openjdk.java.net/~iignatyev//8252532/webrev.0-1/ <http://cr.openjdk.java.net/~iignatyev//8252532/webrev.0-1/> (incremental)

Thanks,
-- Igor

I've decided to put this on one line.
