commit 4b752d52761be4795fd83698b3290df455f0c3ea

    Update CI images to GHC-8.4.4 & cabal-install-2.4.1.0

    Use official bindists, except for Debian 9/Stretch
    http://downloads.haskell.org/debian/ is used. (There are no recent
    GHC/cabal-install for Debian 8/Jessie there)

    Use v2-update/v2-install to install Haskell tools.

    Try to unify structure of the different Dockerfiles, incl installing GHC
    in one step (this will prevent sublayers from existing, making final
    image slightly smaller)
