[buildbot] switch CUDA buildbot to use CUDATestsuiteBuilder.

[tra]

Summary

Now cuda buildbot compiles and runs CUDA tests from llvm test-suite.

[tra]

Do not rename the builder (yet).

[gkistanova]

Only changes in llvm and clang repo would trigger a build on this builder. Is this intentional?

Ideally the build should also be triggered for libcxx and test-suite changes, too, but I'm not sure how to configure that.
In practice llvm+clang changes trigger the builds often enough.

@gkistanova - ping.

The params there do not match what was committed for the factory.
Please check.

Thanks

[tra]

Removed obsolete getCUDATestsuiteBuildFactory() arguments.

Sorry about that. I've updated the patch.

LGTM

Thanks
