Bug#35934      mysql_upgrade calls mysqlcheck with insufficient parameters

The reason for the failures was bug #21205 (fixed in 6.0 by dtoa, but still present in 5.0/5.1).

binlog_row_mix_innodb_myisam resutls are corrected.
The last operations prior the dup error is
TRUNCATE table t2;
Therefore after
--error ER_DUP_ENTRY
INSERT INTO t2 select * from t1;
table t2 must be empty, and that is what the updated results confirm.

Extending bug#40221 regression test: 1. include INSERT 2. convert prim key + autoinc to
unique.
