osutil: fix potential wrong fd close
According to POSIX closedir [1]:
If a file descriptor is used to implement type DIR, that file descriptor
shall be closed.
According to POSIX fdopendir [2]:
Upon calling closedir() the file descriptor shall be closed.
So we should avoid "close(dfd)" after "closedir(dir)". With threads, there
could be a race where an innocent fd gets closed. But Python GIL seems to
help hiding the issue well.
