minigbm: dri: Set the plane sizes on bo creation.

I cut a corner here on a previous patch and apparently it is used.

Since DRI does not give us useful horizontal & vertical strides
(especially considering things like auxiliary surfaces), do this
calculation based on offsets & buffer strides.

BUG=1061315
TEST=test_that graphics_Gbm on Zork.
