Add VBT file to coreboot image.

Browse Source 
Adding the VBT file makes it available through some ACPI memory area
and apparently the VBT contains the information needed by the i915 driver
in order to figure out how to control the screen's backlight.
Without the VBT, we can't control the screen backlight with Fn-F5/Fn-F6
anymore.
