Add "AllPathsVolatile" skpbench bots

Also adds GalaxyS20 to the mix, which wasn't running skpbench
previously.

Also removes the skpbench logic to fail if we don't recognize the
hardware or have specific scripts for it. We don't have time to reverse
engineer every new piece of hardware we want to run on and the general
android script is quite helpful already.
