[Piglit] [v8 10/13] tests/spec: EXT_image_dma_buf_import sample xrgb

[Topi Pohjolainen]

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)
   - used the same refactored common logic as the ARGB test

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

v4 (Eric):
   - add to 'all.tests'
   - removed inclusion of standard EGL entrypoints as there is the
     special dispatcher for the test cases to use

v5 (Eric, Chad):
   - use image external extension for sampling
   - add into all.tests
