Remove old code from service support

We have several places with references to service support which was removed. We need to review our code and remove code related to services. So far I found following:

1) http://cr.openjdk.java.net/~herrick/8212780/webrev.ea6/src/jdk.jpackage/macosx/classes/jdk/jpackage/internal/resources/launchd.plist.template.html
Looks like old file from daemon support. Probably no longer needed.

2) http://cr.openjdk.java.net/~herrick/8212780/webrev.ea6/src/jdk.jpackage/windows/classes/jdk/jpackage/internal/resources/template.iss.html
Line 49-55 - Seems to be related to service support, which is not currently supported. I think this file can be cleanup.
