[Bug-tar] no-overwrite-dir don't preserve permissions of existing directories

Hi,

I expect --no-overwrite-dir to preserve permissions of existing directories when I use tar extract files.

I test with 1.28.

The permissions of existing directory tmpdir/ is 700. In tmpdir.tar it's 777.

After extracting tmpdir.tar, the permissions of tmpdir/ changes to 755 (because of umask 22).

Shouldn't it keep as 700?

bash-4.3$ umask

0022

bash-4.3$ ls -ld tmpdir

drwx------ 2 test test 40 Sep  1 22:41 tmpdir

bash-4.3$ tar tvf tmpdir.tar

drwxrwxrwx test/test   0 2019-09-01 22:41 tmpdir/

bash-4.3$ tar -xvf tmpdir.tar --no-overwrite-dir

tmpdir/

bash-4.3$ ls -ld tmpdir

drwxr-xr-x 2 test test 40 Sep  1 22:41 tmpdir
