Thread: pgsql: Fix a second cause of undersized pallocs for btree_gist indexes

Fix a second cause of undersized pallocs for btree_gist indexes on macaddr.

gbt_macad_union also allocated 12-byte structs where we really need 16.

Per report from Andres Freund.  No back-patch since there's no current
risk of a real problem.
