[8u] RFR 8231463: Fix runtime/RedefineTests/RedefineDoubleDelete.java test in 8u

[Zhengyu Gu]

During the early  JDK-8178870 8u backport, I converted its test case to 
shell script, due to imcompatible of test infrastructure.

This is no longer the case, we should reverse the test case and 
eliminate the shell version.

Bug: https://bugs.openjdk.java.net/browse/JDK-8231463
Webrev: http://cr.openjdk.java.net/~zgu/JDK-8231463/webrev.00/

Test:
   ~/jtreg/bin/jtreg -v:summary -jdk:${TEST_JDK} 
hotspot/test/runtime/RedefineTests

and

  ~/jtreg/bin/jtreg -v:summary -jdk:${TEST_JDK} 
hotspot/test/runtime/RedefineTests/RedefineDoubleDelete.java

Thanks,
