Disable HAVE_DRM_ATOMIC.

weston.log:
Failed to load module: /usr/lib/aarch64-linux-gnu/libweston-5/drm-backend.so: undefined symbol: gbm_surface_set_sync_post
fatal: failed to create compositor backend

Usage of gbm_surface_set_sync_post is guarded by #ifdef HAVE_DRM_ATOMIC in
compositor-drm.c. Calls to gbm_surface_set_sync_post was added by NXP and
isn't an upstream libgbm symbol. Our imx-gpu-viv version doesn't implement
it.

weston-imx-5.0.0 worked fine on chef/stretch as it had libdrm 2.4.74 and
configure.ac checks for >= 2.4.78 to enable HAVE_DRM_ATOMIC:
PKG_CHECK_MODULES(DRM_COMPOSITOR_ATOMIC, [libdrm >= 2.4.78],
    [AC_DEFINE([HAVE_DRM_ATOMIC], 1, [libdrm supports atomic API])],

This change is equivalent of running weston-imx-5.0.0 on chef/stretch.
Other options are reverting the IMX specific calls to gbm_* symbols,
or update to weston-imx-6.0.0 that doesn't have them at all.
