[Buildroot] [v2 3/4] package/redis: Add systemV init script

[Martin Bark]

start-stop-daemon is used to start redis-server as user redis in the
background.  Once redis-server is running we use redis-cli to shutdown
cleanly.

Changes v1 -> v2
 - Change su - redis -c "/usr/bin/redis-cli shutdown" to just
   /usr/bin/redis-cli shutdown since redis users shell is now /bin/false.
   This is ok since redis-cli simply signals redis-server over a socket
   to shutdown.
