Remove references to innodb_file_format.

innodb_file_format=Barracuda is the default in MariaDB 10.2.
Do not set it, because the option will be removed in MariaDB 10.3.

Also, do not set innodb_file_per_table=1 because it is the default.

Note that MDEV-11828 should fix the test innodb.innodb-64k
already in 10.1.
