meta: Respect the driver's maximum number of draw buffers
Commit c1c1cf5f9 added infrastructure for saving and restoring draw
buffer state. However, it universially used MAX_DRAW_BUFFERS, but many
drivers support far fewer than that at limit. For example, the radeon
and i915 drivers only support 1. Using MAX_DRAW_BUFFERS causes meta to
generate GL errors.
