Make -h and -L follow symlinks on extraction of directories.

This means that existing symbolic links won't get overwritten with a
directory, but instead the directory is created/updated with the privs
from the archive at the end of the symlink chain.  Great for unpacking
OpenBSD release tarballs, where you have linked away stuff due to lack of
space on a certain partition etc.
