It's wrong to depend on `${TORCH_LIBRARIES}` as it pulls in explicit
`libcuda.so.1` dependency, which violates the assumption that GPU
accelerated libraries should be loadable with no NVIDIA drivers installed

Instead, make it depend on `torch` target, which includes all necessary
Torch C++ API dependences

When building torchaudio from source, `get_version.sh` from kaldi is executed everytime,
which results in kaldi-bindings to be always rebuilt.

This commit add "if" guard to the part so that they are not always executed.
