Fix python loading of librocm_smi64

The librocm_smi64.so is used for development, while
librocm_smi64.so.MAJOR is used for runtime, thus the python front end
should not be loading the .so binary, but rather the .so.MAJOR binary.

As well, it's good not to hardcode "lib" as some distros will change
this.

rsmiBindings.py is now generated with CMake
