Bug 1003417 - Include testing/mozbase/moz.build from root moz.build file, r=ted

By including the mozbase's moz.build directly in the root moz.build, we are making sure that
mozbase unittests will be found even if there is no build/objdir. This will be useful when
running mozbase tests in their own taskcluster task.
