files: limit the number of attempts at climbing up the directory tree
Doing a chdir("..") will not fail when the root directory is reached,
and when getcwd() keeps failing too, we have no way of knowing when
to stop. So, simply limit the number of attempted chdirs, to avoid
getting into an endless loop.
This avoids the hang in https://savannah.gnu.org/bugs/index.php?47659.
