MDEV-15804 Fix and re-enable MTR test galera.pxc-421

This patch makes two changes: * Remove unnecessary `set SESSION wsrep_sync_wait=0`. Disabling `wsrep_sync_wait` caused the test to fail occasionally, due to subsequent `SELECT`s observing stale values. * Remove redundant `--source include/galera_wait_ready.inc`, `galera_wait_ready.inc` is already included in the above `wait_until_connected_again.inc`
