Use versioned libcuda

Some systems don't have the libcuda.so.1 -> libcuda.so symlink.

Ah, we still support mac, so this will need to be smarter.

I've only been using julia for a few days, so correct me if I'm completely disregarding any infrastructure around this change, but is it not possible to just throw in a try-catch in the case that libcuda.so is not found and instead try libcuda.so.1? I would assume this only needs to be done once, so would not really have much overhead correct?

(Ofcourse, I guess it's also possible to use Libdl to check if libcuda.so exists)

It's possible, but I'd rather just use the correct version. Besides, it would then be embedded in the precompilation image, and not actually performed once each time you load the package, so if the system changes it might still fail.
