Philip Langdale 96d79ff5b5 avutil/cuda_check: Fix non-dynamic-loader implementation
The function typedefs we were using are only present when using the
dynamic loader, which means compilation breaks for code directly
using the cuda SDK.

To fix this, let's just duplicate the function typedefs locally.
These are not going to change.
