renderer/native: Create GBM surfaces with modifiers
Now that we have the list of supported modifiers from the monitor manager (via the CRTCs to the primary planes), we can use this to inform EGL it can use those modifiers to allocate the GBM surface with. Doing so allows us to use tiling and compression for our scanout surfaces. This requires the Mesa commit in: Mesa 10.3 (08264e5dad4df448e7718e782ad9077902089a07) or Mesa 10.2.7 (55d28925e6109a4afd61f109e845a8a51bd17652). Otherwise Mesa closes the fd behind our back and re-importing will fail. See FDO bug #76188 for details. https://bugzilla.gnome.org/show_bug.cgi?id=785779
