Fixes "java.lang.NoSuchMethodError: com.google.inject.Binder.bindListener(Lcom/google/inject/matcher/Matcher;[Lcom/google/inject/spi/ProvisionListener;)V" in maven jobs

[FIXED JENKINS-11256] SurefireArchiver#result doesn't need to be serialized on each remote call. Fixes ConcurrentModificationExceptions in MavenFingerprinter

Using lib-jenkins-maven-embedder version with workaround for https://jira.codehaus.org/browse/MNG-5125.
I still hope this gives some ease regarding JENKINS-11362
