Reintroduce dependency on m2e/archiver integration

This is necessary because some (many?) tests use
META-INF/maven/.../pom.properties to determine version of various
components involved in the test. For example, Verifier Embedded3xLauncher
uses META-INF/maven/org.apache.maven/maven-core/pom.properties
to determine Maven version, but I am sure there are other cases.
