[releng] Make POMs inherit from o.e.r parent POMs

At the moment, this requires that the parent POMs from
org.eclipse.recommenders are installed in your local Maven
repository. So, clone the o.e.r repository and run *once*
"mvn clean install".

Thereafter, you should be able to build this change by
"mvn clean verify"
