innodb.table_flags: Adjust the test case. Due to the MDEV-12873 fix
in 10.2, the corrupted flags for table test.td would be converted,
and a tablespace flag mismatch will occur when trying to open the file.
Cover innodb.table_flags with the new innodb_page_size.combinations
32k and 64k.
dict_sys_tables_type_validate(): Remove an assertion that made a
check in the function redundant. Remove the excessive output to
the error log, as the invalid SYS_TABLES.TYPE value is already being
output.
Add a test case for corrupting SYS_TABLES.TYPE,
and for ROW_FORMAT=REDUNDANT, the unused field SYS_TABLES.MIX_LEN
that must be ignored (InnoDB before MySQL 5.5 wrote uninitialized
garbage to this column).
MariaDB 10.0 appears to validate the SYS_TABLES.TYPE properly.
This is a test-only change.
