[SQL][minor] Simplify data source predicate filter translation.
## What changes were proposed in this pull request?
This is a small patch to rewrite pieces of the predicate filter translation
in DataSourceStrategy. The original code was too excessive with functional
constructs (e.g. unzip) and was very difficult to understand.
## How was this patch tested?
Should be covered by existing tests.
