Subject: [PATCH] nfs-ganesha: add tools output for mount.9P helper

The nfs-ganesha mount.9P helper is a standalone shell script that makes
some aspects of mounting a 9P filesystem easier, e.g. instead of:

  mount -t 9p 192.168.10.2 /mnt -oaname=/home

it allows the familiar syntax:

  mount -t 9P 192.168.10.2:/home /mnt

As the mount helper is independent of the server, it's added as
separate output.
