    dsynth - More pkg dependency fixes
    
    * Fix the depency check based on the depth when recursing through a
      dummy node.  Dummy nodes do not increment the depth.
    
    * In addition, recursing through a dummy node means that the package
      only depends on the default flavor, which is only the first element
      in the idepon list under that dummy node.  Inform the next layer
      that its scan should only iterate one element.
    
    * In addition, when build_find_leaves() recurses through a dummy node
      also use the same mechanism where only the first sub-node is
      checked, because the dependency is (again) against just the default
      flavor.
    
      Note that when doing a 'dsynth everything', all the dependencies
      wind up in the root list, so all the flavors get built.  But when
      building a specific subset of packages, this fix will reduce the
      number of flavors that have to be built as dependencies.
