tar: fix race condition

Problem reported by James Abbatiello in:
https://lists.gnu.org/r/bug-tar/2022-03/msg00000.html
* src/extract.c (make_directories): Do not assume that when
mkdirat fails with errno == EEXIST that there is an existing file
that can be statted.  It could be a dangling symlink.  Instead,
wait until the end and stat it.
