db_query needs column names enclosed in curley brackets

Files: 'groups/generate-utids.php' and 'groups/generate-ntids.php'.

The db queries in those files need to have the column names enclosed in {}.

e.g.:

  db_query("INSERT INTO term_node (nid,tid) VALUES (%d, %d)", $nid, $term);

Needs to be:

  db_query("INSERT INTO {term_node} (nid,tid) VALUES (%d, %d)", $nid, $term);
