Pass system properties to maven repo session (#10117)

The maven repository sessions used by the maven library loader requires
the java.version property to later evaluate the active profiles of
dependencies when downloading them during the plugin loader logic.

This commit fixes this by passing all system properties as a hopefully
future-proof way to provide the required data to said session.
