minigbm: tweak cros-gralloc flags
The Play Store wants a ABGR8888 HW cursor, and we can't in
general support this, so let's ignore the cursor flag rather
than fail the allocation.
We also interpret GRALLOC_USAGE_HW_COMPOSER as BO_USE_SCANOUT
| BO_USE_RENDERING. This fails with YV12, since we can't scanout
from it on Intel/Mediatek. Let's first try to allocate with the
scanout flag enabled and then fall-back to rendering if it's
not supported (i.e, first try overlay but then try OpenGL).
In addition, let's interpret GRALLOC_USAGE_HW_FB the same as
GRALLOC_USAGE_HW_COMPOSER since the framebuffer device
(Chrome in our case) wants to scanout but can also fall back.
