[SPARK-5574] use given name prefix in dir

Browse source 
https://issues.apache.org/jira/browse/SPARK-5574

very minor, doesn't effect external behavior at all.
Note that after this change, some of these dirs no longer will have "spark" in the name at all.  I could change those locations that do pass in a name prefix to also include "spark", eg. "blockmgr" -> "spark-blockmgr"
