gnu: ghc-pandoc-citeproc: Build statically linked executable.origin/wip-haskell-updates

* gnu/packages/haskell-xyz.scm (ghc-pandoc-citeproc)[arguments]: Add
configure flags to build a statically linked executable; add phase
"create-simple-paths-module" to avoid unnecessary inter-output references; add
phase "prepare-static-libraries".
[outputs]: Add "doc" output.
[inputs]: Add static variants of the package closure of all Haskell inputs.
