Subject: [PATCH] Add vitess 21.0.4 package with config/ directory

The upstream nixpkgs vitess package only ships bin/, but
vttestserver and mysqlctl expect $VTROOT/config/init_db.sql and
$VTROOT/config/mycnf/*.cnf at runtime. This package builds vitess
from source and includes the config directory in the output.
