Fix build breakage when using older gbm lacking dmabuf import

The buildbots discovered this issue on Ubuntu 14.04, which carries
libgbm 10.1.3-0ubuntu0.4.  The dmabuf changes need gbm 10.2, so it fails
during build like this:

  src/compositor-drm.c: In function ‘drm_output_prepare_overlay_view’:
  src/compositor-drm.c:984:10: error: variable ‘gbm_dmabuf’ has
  initializer but incomplete type
     struct gbm_import_fd_data gbm_dmabuf = {
            ^
  etc.

Proposed fix is to conditionalize the gbm fd import feature in
compositor-drm.

This fix was suggested by daniels.  I set up a synthetic test
environment to reproduce the issue as found by the buildbots and tweaked
the patch to get it to build both with and without gbm 10.2.
