> DataDrivenDBInputFormat should not query the database when generating only one split

> DataDrivenDBInputFormat runs a query to establish bounding values for each split it generates;
but if it's going to generate only one split (mapreduce.job.maps == 1), then there's no reason
to do this. This will remove overhead associated with a single-threaded import of a non-indexed
table since it avoids a full table scan.
