create alias barufaruku -> valstrax
We use the English names of the Monster Hunter monsters as main tag names when available, and Barufaruku/Valfalk's English name has been confirmed as Valstrax with the reveal of Monster Hunter XX's English release.
EDIT: The tag alias barufaruku -> valstrax (forum #146963) has been rejected by @Hillside_Moose.
