exp/locale/collate: let regtest generate its own collation table. The main table will need to get a slightly different collation table as the one used by regtest, as the regtest is based on the standard UCA DUCET, while the locale-specific tables are all based on a CLDR root table. This change allows changing the table without affecting the regression test.
