[Piglit] [v6 08/12] tests: spec: EXT_image_dma_buf_import planar with multiple fds

[Topi Pohjolainen]

v2:
   - compile only on platforms that have drm (Eric)
   - use standard drm definitions for fourcc instead of duplicated
     local (Daniel, Eric)
   - try to close the export file descriptor and check that it is
     already closed by the EGL stack (Eric, Chad)
   - use helper variables for width, height and cpp instead of
     repeating the magic numbers over and over again (Eric)
   - removed irrelevant quotes of the spec (Eric)
