turnip: Expose a device name similar to the blob.

We add "Turnip" so that users (and vulkan.gpuinfo.org) can distinguish us
without requiring VK_KHR_driver_properties.  This will be a lot more
user-friendly than "FD618", though.

I made some little vk_asprintf helpers, because I figure other drivers
setting up deviceName's will want them too.
