[BUGFIX] Define foreign_match_field definition for test setup

ext:irre_tutorial has two relations to tx_irretutorial_1nff_hotel
from tt_content: One from native field tx_irretutorial_1nff_hotels
and one from within flex for field tx_irretutorial_flexform.

With two relations in place, both need a foreign_match_fields
definition written to the child table to distinguish the two
relations. This is missing for tx_irretutorial_1nff_hotels and
leads to the situation that adding a relation to the flex field
is then shown as relation for the native field, too.

The patch adds a foreign_match_fields definition to the native
field and adapts the .csv test cases accordingly.
