[SPARK-19292][SQL] filter with partition columns should be case-insensitive
on Hive tables
## What changes were proposed in this pull request?
When we query a table with a filter on partitioned columns, we will push
the partition filter to the metastore to get matched partitions directly.
In `HiveExternalCatalog.listPartitionsByFilter`, we assume the column names
in partition filter are already normalized and we don't need to consider case
sensitivity. However, `HiveTableScanExec` doesn't follow this assumption. This
PR fixes it.
## How was this patch tested?
new regression test
