Disallow MERGE cleanly for foreign partitions

While directly targetting a foreign table with MERGE was already
expressly forbidden, we failed to catch the case of a partitioned table
that has a foreign table as a partition; and the result if you try is an
incomprehensible error.  Fix that by adding a specific check.

Backpatch to 15.
