Create wrapper script for wine64 symlink

[Catdaemon]

I was having issues getting shader compilation to work on my M4 Macbook Pro. I followed all the instructions and didn't have any luck at all. After some digging, I found this Reddit post suggesting it works if a script which re-executes wine is used - and it does!

This PR adds a simple wrapper script and symlinks to that instead of wine directly.

I'm not sure why this works (and why it doesn't work otherwise), but the existing symlink created by the script does not, so this is definitely something which should be done (at least until mgfxc or whatever stops trying to use wine64).

@dellis1972 Jumped the gun on this a bit, this breaks the installation for those on older linux distros that still have wine64.

Oh wait, no, my bad, this only executes if wine64 is not found, this is good! Tho we should be able to avoid the symlink entirely by doing:

echo -e "#\!/bin/bash\nwine \"\$@\"" > "$HOME/.winemonogame/wine64"
