GenericBuilder: Add a boolean 'succeeded' parameter to finalize

Previously MockModuleBuilder was checking the module state to see if
it should run a final createrepo, but since eafa93037f, finalize() is
called before changing the module state; add an explicit boolean to
GenericBuilder.finalize() to avoid worrying about ordering.
