Commit 4bea91f21f enabled COPY TO on a partitioned table to read
tuples from its partitions and mapped them to the root table's tuple
descriptor before output. However, it incorrectly built the attribute
map from the root table to the partition.
This commit fixes by building the attribute map from the partition to
the root table, ensuring that partition attributes are correctly
mapped to their corresponding root attributes.
