build-system/haskell: Fix regression in "cabal-revision" input handling.
Previously, (assoc-ref ...) would return a one-element list, leading to
an evaluation error while building the package ("wrong type to apply").
Regression introduced in 7d873f194ca69d6096d28d7a224ab78e83e34fe1.
Reported by Marius Bakke.
* guix/build-system/haskell.scm (haskell-build)[builder]: Adjust
argument to #:cabal-revision.
