bsdgames hack fix

[Bradley Remedios]

I just did some changes to hack to make it work on DSLinux.

1. This works with all current font sizes (4x6, 4x9 and 6x6)

2. I've disabled the locking as it uses the link function, and hard
links are not supported in fat.

3. I've modified it to store the game data in /home/.games/bsdgames/hack.

These changes break the ability to protect against multiple instances
of hack.  This is due to change #2 because the locking in hack uses
the link function.
