python3Packages.torch: Disable MKLDNN on aarch64-darwin
It negatively impacts performance, this is also what official pytorch
build does.
In my test in a Macbook Pro M1 2020, using [pianotrans][1] to transcribe
[cut_liszt.opus][2], transcription time:
Enable mkldnn and disable Accelerate.framework: ~88s
Disable mkldnn and disable Accelerate.framework: ~21s
Disable mkldnn and enable Accelerate.framework: ~9s
The final result is close to using torch-bin.
