[libvirt] [PATCH] Eliminate failure to delete empty storage pools

[Laine Stump]

virStorageBackendFileSystemDelete was incorrectly calling unlink() in
an attempt to remove a directory. It should be calling rmdir()
instead. (remove() would also work, but could potentially succeed on a
non-empty pool if the pool was a symlink to somewhere else).
