[PATCH i-g-t 2/6] lib: Extract ssme common fb create+fill methods into helpers

[ville.syrjala@linux.intel.com]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Several tests do one or more of the followin:
* igt_create_fb() + igt_paint_test_pattern()
* igt_create_color_fb() + igt_paint_test_pattern()
* igt_create_fb() + igt_paint_image()

Extract them into new helpes: igt_create_pattern_fb(),
igt_create_color_pattern_fb(), igt_create_image_fb().
