pyhesiodfs should pass -o nonempty to fuse

[andersk]

pyhesiodfs fails to start up on a nonempty /mit.

root@ringworld:/etc/init.d# /usr/bin/pyhesiodfs /mnt
fuse: mountpoint is not empty
fuse: if you are sure this is safe, use the 'nonempty' mount option
Traceback (most recent call last):
  File "/usr/bin/pyhesiodfs", line 226, in <module>

fuse.FuseError: filesystem initialization failed

From fuse/README:

nonempty

  Allows mounts over a non-empty file or directory.  By default these
  mounts are rejected (from version 2.3.1) to prevent accidental
  covering up of data, which could for example prevent automatic
  backup.
