Remove seemingly unnecessary, '--device=all' in favor of '--device=dri'

It seems a bit excessive to have full device access when only access to the GPU is needed. Don't know exactly if this breaks anything , but prismlauncher launches fine, plays fine, and behaves as before with these changes from what i've seen/played myself

closed this PR because I realized that it was running through software rendering, not hardware, feeling pretty dumb now

Strange. It seems to work now with GPU with only device=dri, I'll leave this open for now then

device=all is needed for controller/gamepad support. Especially important on devices like the Steam Deck

makes sense, i figured there was a catch of some sort, i'll close this PR then
