Use noarch (2nd attempt)

[jakirkham]

Works around issues with CRLF code in the PyPI sdist by making the patch use CRLF. Also works around conda-build's behavior of trying to use a LF patch by manually applying the patch. With these issues handled, the package can be made noarch: python and is. Re-rendered as well to update the CIs accordingly. Should make this easier to maintain going forward.
