Linux hotfix for Version 22.06

This is just a small hotfix that will let the linux version default to a 64-bit build of the game instead of the previous 32-bit version.

This should not affect the majority of players and should not have any visible changes at all but still if you encounter any problems after updating please let us know via e-mail: wizard@swinfjord-games.com or on the steam community discussion board so we can help you and fix the problems as soon as possible. For any ideas or feedback you can also contact us.
