[Piglit] [v7 12/12] tests: spec: EXT_image_dma_buf_import sample argb without miptree

[Topi Pohjolainen]

Tests that one can sample the given buffer without other mipmap
levels by setting texture filtering accordingly.

v2:
   - compile only on platforms that have drm (Eric)
   - use standard drm definitions for fourcc instead of duplicated
     local (Daniel, Eric)
   - removed irrelevant quote of the spec (Eric)
   - use helper variables for width, height and cpp instead
     of repeating the magic numbers over and over again (Eric)
   - used the same refactored common logic as the mipmap ARGB test

v3 (Eric):
   - use properly linked egl-extension calls
