Before this patch, when a system has the CUDA toolkit already installed to its default locations in /usr/local/cuda, there will be two unexpected test case failures:

1. <clang.src>/test/Driver/cuda-detect.cu
2. <clang.src>/test/Driver/cuda-macosx.cu

The reason being that the overall search order was set up to always pick up the path with well-known tools such as ptxas in it; However, the above two test cases require the CUDA path to be the one that is passed to --sysroot.

Moving the sysroot path on top fixes the issue.
