ACCUMULO-2651 Fix rat check problems with maven-invoker-plugin

  Stop causing maven-invoker-plugin to produce build.log in the basedir
  of the test project, which causes RAT check to fail (see RAT-160).
  Change default forkCount=1 to stabilize the default build. We can
  experiment with more forks later.
