Include unversioned libopenblas64_.so for Julia

[mkitti]

This change will include libopenblas.so and libopenblasw64_.so in the tarball.

Checklist

• Used a personal fork of the feedstock to propose changes
• Bumped the build number (if the version is unchanged)
• [-] Reset the build number to 0 (if the version changed)
• Re-rendered with the latest conda-smithy (Use the phrase @conda-forge-admin, please rerender in a comment in this PR for automated rerendering)
• Ensured the license file is being packaged.

This change is meant to assist in updating the Julia feedstock recipe to a recent version of Julia and to also enable compatibility with Julia's binarybuilder.org packages.

Julia's build process as well additional binary packages from Julia reference an unversioned libopenblas64_.so on 64-bit platforms:

Including a symlink that does not have the version suffix .0 would greatly aid in bringing recent versions of Julia to conda-forge.

They are included in openblas package instead of libopenblas package.

They are included in openblas package instead of libopenblas package.

I suppose we can close this then and have julia-feedstock depend on openblas rather than libopenblas.
