Subject: [PATCH] stdlib: Fix return value of zip:zip_get/2

When a file is extracted to a directory, the function returns a map
instead of a file name:

    1> {ok, {_, B}} = zip:zip("", [{"F", ~""}], [memory]), ok.
    ok
    2> {ok, H} = zip:zip_open(B, [{cwd, "/tmp"}]), zip:zip_get("F", H).
    {ok,#{flush => [],name => "/tmp/F"}}
