[Piglit] [v7 08/12] tests: spec: EXT_image_dma_buf_import planar with multiple fds

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