FindCUDA: Fix OSX Clang & no C language enabled
When setting default CUDA_HOST_COMPILER we must dereference CMAKE_C_COMPILER, i.e. /usr/bin/clang should be used instead /usr/bin/cc which is symlink. Otherwise CUDA thinks it is GCC and issues -dumpspecs which is unknown option to Clang. Also in case neither CMAKE_C_COMPILER is defined (project does not use C language) nor CUDA_HOST_COMPILER is specified manually we should skip -ccbin and let nvcc use its own default C compiler.
