[PATCH i-g-t 1/4] lib/igt_kms: Add support for the BACKGROUND_COLOR property.

[Maarten Lankhorst <dev@lankhorst.se>]

The background color is a 64-bits property that contains the ARGB values
of the background with 16 bits for each component.

Add support for the BACKGROUND_COLOR property, and set to pitch black
as the default.
