kfdtest: Improve finding rocm-smi

On Fedora, rocm-smi is a standard package and is installed to /usr/bin
So when run_kfdtest.sh is run this error is produced

find: ‘/opt/rocm*’: No such file or directory

First redirect stderr to dev/null on the original search.
Then fall back to either looking for rocm-smi in BIN_DIR or
look for it in the PATH.
