Subject: [PATCH] Use maven-enforcer-plugin to enforce Maven version

This patch removes the unnecessary declaration of <prerequisites>
section.

As discovered in the mailing list thread linked below the <prerequisites>
section to set a minimal Maven version is deprecated and actually does
not enforce the minimal version. If we need to enforce a minimal Maven
version we need to use the maven-enforcer-plugin instead.
