mb/lenovo/t430s: Enable libgfxinit

Tested on T430s with an external screen connected to every one of the
DP ports (miniDP on mainboard, two DP ports on dock), the GRUB payload
can display on both the external screen and the internal LVDS screen.

This is a copy-paste of I8f270d55 "mb/lenovo/x230: Enable libgfxinit".
