wolf: fix duplicate /home/retro mount — target Steam library path directly

Mounting steam:/home/retro conflicted with the GoW Steam image's own
internal /home/retro mount. Mount steam:/home/retro/.local/share/Steam
instead — this is where steamapps/ and Proton prefixes actually live,
persists all game data, and doesn't collide.
