[9] Review request: JDK-8166958: javafx dll binaries are in the wrong directory in the jmod files

[Kevin Rushforth]

Dave and Chris,

Please review the following build change for Windows to fix the location 
of the .dll files in the jmods:

https://bugs.openjdk.java.net/browse/JDK-8166958
http://cr.openjdk.java.net/~kcr/8166958/webrev.00/

In parallel with your review I still need to sanity test it on Mac and 
Linux to ensure no regressions.
