gbm: gbm_bo_get_handle_for_plane fallback to nonplanar handle

Here is a patch for Mesa 19.0.3 that fixes the issue for me on Fedora 30
x86_64. Essentially the patch returns the nonplanar handle if the API check
fails, making the gbm_bo_get_handle_for_plane() call equivalent to
gbm_bo_get_handle() if requesting plane 0. With this patch, weston starts up
and works correctly for me. Gnome Shell remains unaffected.

Merge request (against master) here:
https://gitlab.freedesktop.org/mesa/mesa/merge_requests/871

This should eventually be backported to 19.0.
