Bug#20166 mysql-test-run.pl does not test system privilege tables creation

 - Build lib/init-db.sql from the output of mysql_create_system_tables
 - Remove mysql-test/init_db.sql and mysql-test/lib/init_db.sql
 - Leave netware/init_db.sql until 5.0 where we should soon have possibility
   to test with mysql-test-run.pl
