updated many dependencies, ghc 8.x

Updated many dependencies, notably secret-sharing which dropped the dep on
polynomial, and so allows building with ghc 8.x.

Did not try to support building with older ghc because the semigroup-monid
transition would make it nontrivial.

Stackage lts-14.25 is a compromise, since the stack shipped in debian (even
unstable) is not able to handle newer ones.
