exfat: support create zero-size directory
This commit adds mount option 'zero_size_dir'. If this option
enabled, don't allocate a cluster to directory when creating
it, and set the directory size to 0.
On Windows, a cluster is allocated for a directory when it is
created, so the mount option is disabled by default.
