Don't bundle Python dependencies on osx

[xhochy]

Since https://github.com/conda-forge/pytorch-cpu-feedstock/pull/210, this packages bundles all Python dependencies inside the package on osx. Therefore, I would mark all of the osx builds since then as broken. Linux shouldn't be affected.

Hi! This is the friendly automated conda-forge-linting service.

I just wanted to let you know that I linted all conda-recipes in your PR (recipe) and found it was in an excellent condition.

I do have some suggestions for making it better though...

For recipe:

• It looks like the 'libtorch' output doesn't have any tests.

eek, sorry.

btw, I would almost prefer it if you pressed merge so it doesn't retrigger the linux builds on the big CIs ;) but that is your choice!
