Move hostname ip entry to the end of /etc/hosts

spymemcached package is FTBFS because a test expects a reverse lookup of 127.0.0.1 to return localhost, but current /etc/hosts configuration returns the hostname instead.

Let's move this hostname/ip entry to the end of /etc/hosts so the reverse lookup of 127.0.0.1 returns localhost, which makes sense to be the default case usually.
