virtio-gpu-3d: add support for second capability set (v4)
Due to a kernel bug we can never increase the size of capability set 1, so introduce a new capability set in parallel, old userspace will continue to use the old set, new userspace will start using the new one when it detects a fixed kernel. v2: don't use a define from virglrenderer, just probe it. v3: fix compilation when virglrenderer disabled v4: fix style warning, just use ?: op instead.
