use actual value of groupId when importing jboss-eap-parent with import scope

jboss-eap-parent artifact is being imported (import scope) in the dependency management section in the root pom.xml and the groupId of jboss-eap-parent is defined as ${project.groupId}.

If, for example, you try to use the XP2 pom as a parent of a different project, the ${project.groupId} is going to be resolved as the groupId of this project and not the value that it should be (org.jboss.eap)

To avoid this problem, I suggest changing this variable to the actual value org.jboss.eap instead of using ${project.groupId}
