#205413 fix for 7.1

A regression has been discovered

http://netbeans.org/bugzilla/show_bug.cgi?id=205413

caused last week by changeset
http://hg.netbeans.org/main-silver/rev/0dc87a0933c3

It partly broke the JavaFX InteropSample. This sample
is particularly important because it is the only one supplied to
show Swing-JavaFX interoperability.

The fix is simple, consists in returning InteropSample's build.xml to 
the state
before last week:

http://hg.netbeans.org/jet-main/rev/8b96c405ea63

The fix is clearly localized and can not affect any other code.
Yet it is important to integrate, as without it the InteropSample
would not produce all the deployment files as described in
the documentation that is presented to users when opening the sample.
