build-system/haskell: Add 'extra-directories' keyword.

See <https://bugs.gnu.org/39309>.

* guix/build-system/haskell.scm (lower): Include the transitive
propagated inputs of 'extra-directories' inputs.
(haskell-build): Add the 'extra-directories' keyword and pass it through
to the builder.
* guix/build/haskell-build-system.scm (configure): Use it to select
which inputs get passed via 'extra-include-dirs' and 'extra-lib-dirs' to
Cabal.
* gnu/packages/haskell-xyz.scm (ghc-alsa-core, ghc-hmatrix,
ghc-hmatrix-gsl, ghc-hslua, ghc-iwlib, ghc-libyaml, ghc-ncurses,
ghc-openglraw, ghc-x11, ghc-x11-xft, ghc-zlib): Set 'extra-directories'.
* gnu/packages/haskell-crypto.scm (ghc-digest, ghc-hsopenssl): Likewise.
