proton: Sync pfx creation and create a guard file.

Browse Source 
Due to unlucky power off or a crash crash when first starting the game
the prefix can end up in corrupted state with no obvious way of
troubleshooting.

This is an attempt at ensuring that the prefix was created successfully
and force-recreate it if it wasn't.
