cube-tex: make use of modifiers

Fixes rendering issues with mode rgba on etnaviv. I have applied
the same change for nv12 variants but they are not supported on
etnaviv.

v1 -> v2:
 - check if EGL_EXT_image_dma_buf_import_modifiers is supported
 - use weak function trick for gbm_bo_get_modifier(..)

v2 -> v3:
 - check if modifier != DRM_FORMAT_MOD_INVALID
