Add a flag to disable Sodium checking for RivaTuner

[Niterux]

I would like to add this flag to Sodium to disable its check to RTSS as I use RTSS along side Minecraft all of the time and I have no issues pertaining to log spam or performance problems.

from what i can tell in the screenshot however is that rivatuner isnt displaying an overlay, drawing the overlay itself is done via legacy opengl calls which is what causes havoc (unless i am missing something and rivatuner is drawing something in minecraft)

Since we don't really know what conditions will cause the problem, I guess that I am okay with adding a flag. At some point we should consider moving these flags into a separate config file, or something.
