Roman Stratiienko 7ae4a2ae34 u_gralloc/fallback: Extract modifier from QCOM native_handle
After Turnip moved to u_gralloc, some users started complaining
about issues. It turns out that modern platforms do not have
grallocs{0,1} but have gralloc4 only. There's no
known way to build mesa3d with gralloc4 support using NDK.

So we add this workaround to fallback gralloc to mimic the original
behavior of the Turnip driver before switching to u_gralloc.
