`estargz.Build` currently doesn't support duplicated entries in the input tar. But there are images that contain duplicated entries in a layer and we currently cannot optimize these layers. GNU tar supports duplicated entries by replacing the former entry with the later one. (https://www.gnu.org/software/tar/manual/html_node/multiple.html) This commit takes the simillar approach for supporting duplicated entries. Signed-off-by: Kohei Tokunaga <ktokunaga.mail@gmail.com>
