cuttlefish binary not copying when schema discovery is disabled

[Heinz N. Gies]

This fixes it:

 65     Overlays1 = case {lists:keyfind(schema_discovery, 1, CFConf),
 66                       lists:keyfind(overlay, 1, Relx)} of
 67                     {{schema_discovery, false}, {overlay, Overlays}} ->
 68                         Overlays ++ overlays(Name, CuttlefishBin, Overlays, []);
 69                     {{schema_discovery, false}, _} ->
 70                         overlays(Name, CuttlefishBin, [], []);
 71                     {_, {overlay, Overlays}} when is_list(Overlays) ->
 72                         Overlays ++ overlays(Name, CuttlefishBin, Overlays, AllSchemas);
 73                     _ ->
 74                         overlays(Name, CuttlefishBin, [], AllSchemas)
 75                 end,
