Auto takes the RADV pair on a Samsung Xclipse, with the system route as its fallback

A tester's Galaxy S24 FE (Xclipse 940) boots to Steam with the RADV-Xclipse pair, where the
system-driver route fails at Steam's OpenGL (glamor and GLX cannot load a driver). Auto now
downloads and selects RADV on an Xclipse like the Mali pairs, and falls back to the system route
only when RADV is not published. #570's reset of both drivers at each start no longer undoes an
open driver pair. PowerVR (vulkan.powervr.so) keeps the system driver as before.
