Subject: [PATCH] Support FindTarantool to look for nonsystem tarantool

If a user have tarantool installed into custom directory he may specify
path to tarantool installation using `TARANTOOL_DIR` variable like this:

```bash
tarantoolctl rocks TARANTOOL_DIR=/path/to/tarantool/ install kafka
```

Luarocks will bypass this variable to cmake, which will use is to find
its header files
