Minor refactor of nodeAgg.c.
* Separate calculation of hash value from the lookup.
* Split build_hash_table() into two functions.
* Change lookup_hash_entry() to return AggStatePerGroup. That's all
the caller needed, anyway.
These changes are to support the upcoming Disk-based Hash Aggregation
work.
