lwjgl2 optionally requires the xrandr command line utility on linux, but
does not check if the executable actually exists before trying to use
it. We can force it to fall back to the xf86videomode implementation
by checking for the executable ourselves, and force disabling xrandr
with this boolean [1] if it does not exist.
