llvmpipe: Add handle export for resource_get_param
2dcc9c7f from !6639 (merged) added a resource_get_param hook for llvmpipe, which was nice since it gave lavapipe more features. One of those features was not exporting llvmpipe textures, so those parts were stubbed out and landed in an assert(0).
This completely broke kms_swrast (llvmpipe+GBM) on non-release builds, since that definitely does need to export llvmpipe textures.
The query codepath which caused this explosion does fall back to resource_get_handle() - which is how it worked previously - but not all callers do this, so just do what all other drivers implementing resource_get_param() do and open-code the translation.

@jadahl I've gone for a more conservative approach here, can you please double-check it still works?
