The packager will determine the root modules and invoke jlink to create the resulting image for a non-modular application.  To get the root modules for a release, one solution is to generate that list at build time.

This patches provides an API to get a ModuleFinder configured for link phase and JDK-8147894 will refresh the jlink API to support that.

I’ll push as is and it should be looked at together when the jlink API is updated.
