SWORD25: Fix error after changing language in-game with the data file…

… distributed by ScummVM

Changing the language in-game causes the language to be set for the target in the
scummvm.ini file. Then the next time we try to start the engine, if was causing an error
(Sword25 failed to instantiate engine: Game data not found) because there was no match
for the path and language in the detection table. Setting the language to Unknown in
the detection table for this multilingual data file fixes the issue.
