[fix] wrong lsb init configuration

the lsb init configuration contains no data for 'Required-Stop'. fixed
this by adding the same data that is already used by 'Required-Start'.
[fix] wrong chkconfig priorities

the current chkconfig priorities are causing the docker container to be
stopped and removed after the docker daemon has stopped. obviously this
does not work. fixed this by lowering the stop priority to 15 instead of
97.
