Bug#994774: Working SysV Init Script

[Chris Dos]

I pulled the SysV init script included in the Ganesha 3.5 source tarball:
nfs-ganesha-3.5/src/scripts/init.d/nfs-ganesha.debian8

I had to make a couple of minor changes in order for it to work.  I changed
the LOCK file location from /var/lock/subsys to /var/lock.  I changed the
status call to use status_of_proc.

I've attached the working init script.
