minigbm: virtio-gpu: add more supported formats

Browse source 
There is a desire to use virtio-gpu + Android with kernel v4.4. Let's
make it like the vgem backend, which aligns widths and heights to
64-pixel boundaries to support LLVM requirements.

BUG=chromium:616275
TEST=no crashes when running Android with amd64-generic-cheets
