Fix GPU_ARCHS setting in Java CMake build and CMAKE_CUDA_ARCHITECTURE…

…S in Python package build. (#13117)

Changes the `GPU_ARCHS` setting in `pom.xml` from `ALL` to `RAPIDS` per recent change in rapidsai/rapids-cmake/pull/397

The Python package build requires CUDA as of the addition of string UDFs, which added compilation of ptx code to the Python build. Therefore CMAKE_CUDA_ARCHITECTURES must be set appropriately even when only the Python package is being built. rapidsai/rapids-cmake#397 requires a nonempty string value to be used if the variable is set at all. This PR updates build.sh to include the appropriate default when only the Python build is requested.
