MODCONF-110: Don't generate ModuleName.java for mod-configuration-client

mod-configuration-client is a software library, therefore it should not ship with a ModuleName.java.

The module that uses mod-configuration-client as a dependency needs to create an own ModuleName.java with its own name.

(cherry picked from commit 13748ee)
