import: hackage: Allow version at the beginning of cabal file.
Fix a corner case, uncovered by the hedgehog package, which has the version field at the beginning of its cabal file. This causes a pattern match failure. * guix/import/hackage.scm (latest-release): Match version at beginning of expression too.
