derivations: Use a regular hash table for the module cache.

The hit rate of the 'add-data-to-store' cache goes from 10% to 4% on:

  guix build -e '(@@ (gnu packages libreoffice) libreoffice)' -nd

* guix/derivations.scm (%module-cache): Turn into a regular hash table.
It didn't make sense to use a weak-value hash table given that values
are pairs.
