MINOR: Pass absolute directory path to RocksDB.open
The method `RocksDB.open` assumes an absolute file path. If a relative path
is configured, it leads to an exception like the following:
```
org.apache.kafka.streams.errors.ProcessorStateException: Error opening
store CustomerIdToUserIdLookup at location
./tmp/rocksdb/CustomerIdToUserIdLookup
at org.rocksdb.RocksDB.open(Native Method)

```
Is there any risk to always fetching the absolute path as proposed here?
Let me know if you think this requires a JIRA issue or a unit test. I
started working on a unit test, but don't know of a great solution for writing
out a file to a relative directory.
