build-system/haskell: CONFIG_SHELL env variable.

For Cabal packages with "build-type: Configure", a configure shell
script is run to set up build parameters.  These scripts need the
CONFIG_SHELL environment variable to be set to function properly.

* guix/build/haskell-build-system.scm (configure): Set CONFIG_SHELL if
  necessary.
