When MySQL 5.7.9 (and MariaDB Server 10.2) introduced
innodb_default_row_format and made ROW_FORMAT=DYNAMIC the default,
it became possible to create any ROW_FORMAT tables in the InnoDB
system tablespace, except ROW_FORMAT=COMPRESSED.

In MySQL 5.7, it is possible to create ROW_FORMAT=DYNAMIC
tables when TABLESPACE=innodb_system is explicitly specified.
Because MariaDB Server 10.2 does not support the MySQL 5.7
TABLESPACE=innodb_system attribute for tables, we should allow
ROW_FORMAT=DYNAMIC when innodb_file_per_table=0.

Also, remove the test innodb_zip.innodb-create-options, which was
an outdated copy of innodb_zip.create_options.
