Yes. I would always want to bundle the modules up. I'll replace it with 
ifdef BUILD_MODULES.

Some time in the future, I would want some way to specify what modules 
to build and install on top of the base-image and perform the 
appropriate testing.  jdk-module-image won't need to be bundled at that 
time.

Thanks for the review.
