tar: fix -x --overwrite bug (no --dereference, ! O_NOFOLLOW)

This bug was discovered on Solaris 8.  On older hosts lacking
O_NOFOLLOW, tar -x --overwrite (without --dereference) follows
symbolic links, causing the "extract over symlinks" test to fail.

* src/extract.c (open_output_file): If O_NOFOLLOW is needed but
does not work, check for a symlink separately.
