Add glusterd service init script for old glusterfs packages

In version >=3.11.3 of glusterfs package (on Debian) 'glusterfs-server'
service name has been changed to 'glusterd'. To keep things simple
the patch creates a symlink named '/etc/init.d/glusterd' which is
pointing out to /etc/init.d/glusterfs-server script for old version of
glusterfs package so 'glusterd.service' service name can be used for
old and new versions of glusterfs.
