Fix side effect of reverting Cassandra drivers

lz4 and snappy does not have any tags, and that had confused `git describe`.
This version still have following problems:

- Current directory set to /var/lib/basho_bench
  When dpkg-installed basho_bench try tor start, its current directory is
  set as somewhere like /var/lib/basho_bench/lib/basho_bench-*. That is
  where the basho_bench script runs `cd` inside, because just to load
  correct beam files to run whole basho_bench.
  The workaround is to just specify `-d` option with absolute path.

- Currently basho_bench has limited number of example configs installed in
  /etc/basho_bench. It should be installed in other place like
  `/usr/share/basho_bench/examples` but node_package seems not supporting
  such installation other than manpages.
