Allow saving scores in /var/games

Description
Enough users have complained about scores moving to the home directory that it would be good to provide an option to revert to storing scores in /var/games. The option is only of interest to system administrators so no need to expose it in the UI; it can be a single gsetting shared between all games.
This means we have to go back to using setgid on the games binaries. I frankly don't see the problem with that -- if you have a games group with access to sensitive data, you really need to rethink that.
