Update arkwork-curve wb fork to current arkwork-algebra master

[drskalman]

With new changes to arkworks the wb curve branch doesn't compile anymore. We should reflect the changes done in arkwork-algebra/test-curve here both for BLS12-377 and BLS-381. And make a pull request agaist arkwork-rs/curves after.
