[bug#70923] [PATCH 09/13] import: hackage: Use 'maybe-list-field' procedure.

[Herman Rimm via Guix-patches via <guix-patches@gnu.org>]

* guix/import/hackage.scm (maybe-inputs, maybe-arguments): Delete
procedures.
(hackage-module->sexp): Use 'maybe-list-field' and
'maybe-upstream-inputs' procedures.
* tests/hackage.scm: Fix whitespace and replace 'quasiquote' with
'list'.
