RFR: JDK-8233270: Add support to jtreg helpers to unpack packages

[Alexander Matveev]

Hi Alexey,

1) Remove this file:
test/jdk/tools/jpackage/helpers/jdk/jpackage/test/JavaTool.java.rej
2) Agree with Phil, they probably should be pushed as two separate bugs.
3) Do you know how to run installer tests with new changes? It is not 
clear from code.

Changes itself looks fine.

Thanks,
Alexander
