Use maven-enforcer-plugin to enforce minimum versions

<prerequisites> tags are not inherited by children. We can use
maven-enforcer-plugin to really check the Maven version.

See http://stackoverflow.com/q/18055009/4227853 .

It's not really clear if <prerequisites> is really deprecated
or not, but "mvn versions" complains if it is not present, so
we can at least leave it in the top-level pom.

While at it we can also configure it to check for the minimum
Java version the project needs (1.8).
