clients/simple-dmabuf-drm: import with dmabuf modifiers

Browse Source 
mesa's freedreno driver supports importing dmabufs with format
DRM_FORMAT_NV12 and DRM_FORMAT_MOD_SAMSUNG_64_32_TILE modifier.
demonstrate weston modifier advertising and import path using this
combination when run with --import-format=NV12.

v2:
 - hard code format if platform doesn't implement
   EGL_EXT_image_dma_buf_import_modifiers and cannot advertise
   format/modifier support.
 - squash using valid frame data to fill dmabuf planes
