Errors while running CTest

Start by reproducing the failure with ./build.sh and CTest, then inspect the [xclbinutil]:ps-kernel test under build/Debug/unit-tests/xclbinutil/ps-kernel and its runme.log. Check how the test uses pskernel.so and the --add-pskernel command. Done means the test completes successfully and all 18 CTest tests pass.
