[Piglit] [v6 10/12] tests: spec: EXT_image_dma_buf_import sample argb with miptree

v2:
- compile only on platforms that have drm (Eric)
- use standard drm definitions for fourcc instead of duplicated
local (Daniel, Eric)
- use helper variables for width, height and cpp instead
of repeating the magic numbers over and over again (Eric)
- removed irrelevant quote of the spec (Eric)
- refactored mostly into common part that can be re-used in
the follow-up patches
- now using Eric's piglit_build_simple_program
