game: auto-pick metin wine prefix when WINEPREFIX is unset

Browse Source 
The default ~/.wine prefix lacks tahoma + d3dx9 + vcrun, which makes the
client run with invisible fonts and missing renderer DLLs — exactly what
Jan hit when running the launcher against a fresh install dir on Fedora.

If the parent shell already set WINEPREFIX, honor it. Otherwise fall
back to ~/metin/wine-metin, which is what
m2dev-client/scripts/setup-wine-prefix.sh prepares with the right
runtime deps. The fallback is guarded on the dir existing, so
deployments without that setup are a no-op rather than a broken prefix.
