[Piglit] [v7 09/12] tests: spec: EXT_image_dma_buf_import planar with single fd

[Topi Pohjolainen]

Create a planar image where all the planes are located in the
same dma buffer, just in different offsets.

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 and height (Eric)
   - use helper variable for reporting the result (Chad)

v3:
   - use properly linked egl-extension calls (Eric)
   - check for EBADF and not just for close()-failure (Daniel)
