cmpn: Don't publish osgi.cmpn
cmpn: Don't publish osgi.cmpn

Since we no longer want to encourage the use of osgi.cmpn, we no
longer publish it to Maven Central.

We still build in our build as the project is a collection point for
compendium specs and we want the aggregated javadoc for compendium.
