bugfix: schemas/util.sql: mk_map_table(): add trigger to remove metadata value entries from the map spreadsheet as it's being imported, since these do not correspond to actual columns in the staging table and will produce an error when trying to rename nonexistent columns to them. note that these entries will still need to be included properly in VegBIEN.csv, which will require changes to the VegBIEN.csv make target.
