Subject: [PATCH] Add heuristics to predict the runner for Lutris service games

Pretty simple; if there's just one platform, and it is Windows or Linux or MS-DOS, we guess 'wine' or 'linux' or 'dosbox'; otherwise we just give up.

Sadly most Lutris service games seem to have multiple platforms. Darn you, portability, darn you to heck!

We can tweak this to be more opinionated later, if desired.
